Currently, hardened usercopy performs dynamic bounds checking on slab
cache objects. This is good, but still leaves a lot of kernel memory available to be copied to/from userspace in the face of bugs. To further restrict what memory is available for copying, this creates a way to whitelist specific areas of a given slab cache object for copying to/from userspace, allowing much finer granularity of access control. Slab caches that are never exposed to userspace can declare no whitelist for their objects, thereby keeping them unavailable to userspace via dynamic copy operations. (Note, an implicit form of whitelisting is the use of constant sizes in usercopy operations and get_user()/put_user(); these bypass all hardened usercopy checks since these sizes cannot change at runtime.) This new check is WARN-by-default, so any mistakes can be found over the next several releases without breaking anyone's system. The series has roughly the following sections: - remove %p and improve reporting with offset - prepare infrastructure and whitelist kmalloc - update VFS subsystem with whitelists - update SCSI subsystem with whitelists - update network subsystem with whitelists - update process memory with whitelists - update per-architecture thread_struct with whitelists - update KVM with whitelists and fix ioctl bug - mark all other allocations as not whitelisted - update lkdtm for more sensible test overage -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: Kees Cook <kees@outflux.net> iQIcBAABCgAGBQJabvleAAoJEIly9N/cbcAmO1kQAJnjVPutnLSbnUteZxtsv7W4 43Cggvokfxr6l08Yh3hUowNxZVKjhF9uwMVgRRg9Nl5WdYCN+vCQbHz+ZdzGJXKq cGqdKWgexMKX+aBdNDrK7BphUeD46sH7JWR+a/lDV/BgPxBCm9i5ZZCgXbPP89AZ NpLBji7gz49wMsnm/x135xtNlZ3dG0oKETzi7MiR+NtKtUGvoIszSKy5JdPZ4m8q 9fnXmHqmwM6uQFuzDJPt1o+D1fusTuYnjI7EgyrJRRhQ+BB3qEFZApXnKNDRS9Dm uB7jtcwefJCjlZVCf2+PWTOEifH2WFZXLPFlC8f44jK6iRW2Nc+wVRisJ3vSNBG1 gaRUe/FSge68eyfQj5OFiwM/2099MNkKdZ0fSOjEBeubQpiFChjgWgcOXa5Bhlrr C4CIhFV2qg/tOuHDAF+Q5S96oZkaTy5qcEEwhBSW15ySDUaRWFSrtboNt6ZVOhug d8JJvDCQWoNu1IQozcbv6xW/Rk7miy8c0INZ4q33YUvIZpH862+vgDWfTJ73Zy9H jR/8eG6t3kFHKS1vWdKZzOX1bEcnd02CGElFnFYUEewKoV7ZeeLsYX7zodyUAKyi Yp5CImsDbWWTsptBg6h9nt2TseXTxYCt2bbmpJcqzsqSCUwOQNQ4/YpuzLeG0ihc JgOmUnQNJWCTwUUw5AS1 =tzmJ -----END PGP SIGNATURE----- Merge tag 'usercopy-v4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux Pull hardened usercopy whitelisting from Kees Cook: "Currently, hardened usercopy performs dynamic bounds checking on slab cache objects.

ARM: 8744/1: don't discard memblock for kexec
Discarding the memblock arrays usually works, but causes problems
with kexec, as pointed out by this kbuild warning:
WARNING: vmlinux.o(.text+0x7c60): Section mismatch in reference from the function machine_kexec_prepare() to the function .meminit.text:memblock_is_region_memory()
This lets us keep the memblock structures around whenever kexec
is enabled, but otherwise still drops them.

arm: Implement thread_struct whitelist for hardened usercopy
While ARM32 carries FPU state in the thread structure that is saved and restored during signal handling, it doesn't need to declare a usercopy whitelist, since existing accessors are all either using a bounce buffer (for which whitelisting isn't checking the slab), are statically sized (which will bypass the hardened usercopy check), or both.

dma-mapping: move swiotlb arch helpers to a new header
phys_to_dma, dma_to_phys and dma_capable are helpers published by architecture code for use of swiotlb and xen-swiotlb only. Drivers are not supposed to use these directly, but use the DMA API instead. Move these to a new asm/dma-direct.h helper, included by a linux/dma-direct.h wrapper that provides the default linear mapping unless the architecture wants to override it. In the MIPS case the existing dma-coherent.h is reused for now as untangling it will take a bit of work. Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: Robin Murphy <robin.murphy@arm.com> |

ARM: 8723/2: always assume the "unified" syntax for assembly code
The GNU assembler has implemented the "unified syntax" parsing since 2005. This "unified" syntax is required when the kernel is built in Thumb2 mode. However the "unified" syntax is a mixed bag of features, including not requiring a `#' prefix with immediate operands. This leads to situations where some code builds just fine in Thumb2 mode and fails to build in ARM mode if that prefix is missing. This behavior discrepancy makes build tests less valuable, forcing both ARM and Thumb2 builds for proper coverage. Let's "fix" this issue by always using the "unified" syntax for both ARM and Thumb2 mode. Given that the documented minimum binutils version that properly builds the kernel is version 2.20 released in 2010, we can assume that any toolchain capable of building the latest kernel is also "unified syntax" capable. Whith this, a bunch of macros used to mask some differences between both syntaxes can be removed, with the side effect of making LTO easier.

ARM: SoC platform updates for 4.15
Most of the commits are for defconfig changes, to enable newly added drivers or features that people have started using. For the changed lines lines, we have mostly cleanups, the affected platforms are OMAP, Versatile, EP93xx, Samsung, Broadcom, i.MX, and Actions. The largest single change is the introduction of the TI "sysc" bus driver, with the intention of cleaning up more legacy code. Two new SoC platforms get added this time: - Allwinner R40 is a modernized version of the A20 chip, now with a Quad-Core ARM Cortex-A7. According to the manufacturer, it is intended for "Smart Hardware" - Broadcom Hurricane 2 (Aka Strataconnect BCM5334X) is a family of chips meant for managed gigabit ethernet switches, based around a Cortex-A9 CPU. Finally, we gain SMP support for two platforms: Renesas R-Car E2 and Amlogic Meson8/8b, which were previously added but only supported uniprocessor operation. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJaDgf/AAoJEGCrR//JCVIntcMQAKI2q0Dr2giWtKSoH9GDh5co 137MamTj1YExIcmtbDVO22jV4WSKhIduo+rRBYmQ/uvrkUe9tf7I172JeAIzMzGf HGYJ6fxpaEMUAbUlNcjuXJc7jQXNKLBK2X9CMuwXX3X3HddxKkL38D1d/Mxv5RGu G1pEe0j734Qio9LpACnb0xnluwyUBJOYNwo7Agj5RWzOrXZ+TdwkiIW0JdQiG7Z5 wabzDa7OW1maB+hVYMAM3wHcqO7DKEvGvjYLRoT12cnOLXq7BNbXqXFufuMUNmNE ABhWA1h9SYrXT3n5pQLwoonvvTsI7KXCefrZ0wuxbjrdD4yGW1gmgpRee9RfoggD A6/62wpmSS61X5QWC6BLEa5v/o5NKewndyWhnjLllgJX8sRUbnPQa/xKv7ngdlN5 7YL5HWoNpMQv7fEweSc6j5l/F3yRBndn9TpeKiqCiUiNDrIGlZYhYKIcr9rGESFk pu2KgK+e9+1k7F4s7LotsA65Q5bZIMveyyVtx0XHXz1G4O8NksoQCLJ3wcqQ2pzI WpyOO5R1CNltPhKGC7EP3OZcIMlCtCnsNcedb/AGHgPS+ert2UxBnlSeSMBQlLZY 4fDwEAlA1qx9PuG9N3xrK/gAFiFLafK2sNxtVc7NSmXkkdm3xgJ95Y9sa72Y2qNO rU2LL8SM7cOwhXHrlEFB =jlJ2 -----END PGP SIGNATURE----- Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform updates from Arnd Bergmann: "Most of the commits are for defconfig changes, to enable newly added drivers or features that people have started using.

License cleanup: add SPDX GPL-2.0 license identifier to files with no license
Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

ARM: ep93xx: switch to SPARSEMEM
The EP93xx has four chip selects that can be used for the SDRAM memory. These chip selects are decoded to specify an address domain: SDCS3 0x00000000-0x0fffffff with Boot Option ASDO=1 SDCS0 0xc0000000-0xcfffffff SDCS1 0xd0000000-0xdfffffff SDCS2 0xe0000000-x0efffffff SDCS3 0xf0000000-0xffffffff with Boot Option ASDO=0 Because of the row/column/bank architecture of SDRAM, the mapping of these memories into the processor's memory space is discontiguous. Most ep93xx systems only use one of the chip selects. For these systems, ARCH_HAS_HOLES_MEMORYMODEL has worked fine to handle the discontiguous memory. But, some of the TS-72xx boards use multiple chip selects. The TS-7300 in particular uses SDCS3 (with ASDO=1) and SDCS2. On that system with ARCH_HAS_HOLES_MEMORYMODEL the SDCS2 memory does not get handled correctly and results in the system not booting. Change the EP93xx to ARCH_SPARSEMEM_ENABLE. This handles the discontiguous memory for all configurations. This has been tested on the following ep93xx platforms: EDB9307A with 64 MiB on SDCS0 Vision EP9307 with 64 MiB on SDCS0 TS-7300 with 64 MiB on SDCS3 (with ASDO=1) and 64 MiB on SDCS2 sim.one with 64 MiB on SDCS0 Signed-off-by: H Hartley Sweeten <hsweeten@visionengravers.com> Tested-by: Linus Walleij <linus.walleij@linaro.org> Cc: Russell King <linux@armlinux.org.uk> Tested-by: Florian Fainelli <f.fainelli@gmail.com> Tested-by: Alexander Sverdlin <alexander.sverdlin@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> |

ARM: XIP kernel: store .data compressed in ROM
The .data segment stored in ROM is only copied to RAM once at boot time and never referenced afterwards. This is arguably a suboptimal usage of ROM resources. This patch allows for compressing the .data segment before storing it into ROM and decompressing it to RAM rather than simply copying it, saving on precious ROM space. Because global data is not available yet (obviously) we must allocate decompressor workspace memory on the stack. The .bss area is used as a stack area for that purpose before it is cleared. The required stack frame is 9568 bytes for __inflate_kernel_data() alone, so make sure the .bss is large enough to cope with that plus extra room for called functions or fail the build. Those numbers were picked arbitrarily based on the above 9568 byte stack frame: 10240 (2.5 * PAGE_SIZE): used to override -Wframe-larger-than whose default value is 1024. 12288 (3 * PAGE_SIZE): minimum .bss size to contain the stack.

ARM: NOMMU: Introduce dma operations for noMMU
R/M classes of cpus can have memory covered by MPU which in turn might configure RAM as Normal i.e. bufferable and cacheable. It breaks dma_alloc_coherent() and friends, since data can stuck in caches now or be buffered. This patch factors out DMA support for NOMMU configuration into separate entity which provides dedicated dma_ops. We have to handle there several cases: - configurations with MMU/MPU setup - configurations without MMU/MPU setup - special case for M-class, since caches and MPU there are optional In general we rely on default DMA area for coherent allocations or/and per-device memory reserves suitable for coherent DMA, so if such regions are set coherent allocations go from there. In case MMU/MPU was not setup we fallback to normal page allocator for DMA memory allocation. In case we run M-class cpus, for configuration without cache support (like Cortex-M3/M4) dma operations are forced to be coherent and wired with dma-noop (such decision is made based on cacheid global variable); however, if caches are detected there and no DMA coherent region is given (either default or per-device), dma is disallowed even MPU is not set - it is because M-class implement system memory map which defines part of address space as Normal memory.

ARM: 8678/1: ftrace: Adds support for CONFIG_DYNAMIC_FTRACE_WITH_REGS
The DYNAMIC_FTRACE_WITH_REGS configuration makes it possible for a ftrace operation to specify if registers need to saved/restored by the ftrace handler. This is needed by kgraft and possibly other ftrace-based tools, and the ARM architecture is currently lacking this feature. It would also be the first step to support the "Kprobes-on-ftrace" optimization on ARM. This patch introduces a new ftrace handler that stores the registers on the stack before calling the next stage. The registers are restored from the stack before going back to the instrumented function. A side-effect of this patch is to activate the support for ftrace_modify_call() as it defines ARCH_SUPPORTS_FTRACE_OPS for the ARM architecture.

efi/arm: Enable DMI/SMBIOS
Wire up the existing arm64 support for SMBIOS tables (aka DMI) for ARM as well, by moving the arm64 init code to drivers/firmware/efi/arm-runtime.c (which is shared between ARM and arm64), and adding a asm/dmi.h header to ARM that defines the mapping routines for the firmware tables. This allows userspace to access these tables to discover system information exposed by the firmware. It also sets the hardware name used in crash dumps, e.g.: Unable to handle kernel NULL pointer dereference at virtual address 00000000 pgd = ed3c0000 [00000000] *pgd=bf1f3835 Internal error: Oops: 817 [#1] SMP THUMB2 Modules linked in: CPU: 0 PID: 759 Comm: bash Not tainted 4.10.0-09601-g0e8f38792120-dirty #112 Hardware name: QEMU KVM Virtual Machine, BIOS 0.0.0 02/06/2015 ^^^ NOTE: This does *NOT* enable or encourage the use of DMI quirks, i.e., the the practice of identifying the platform via DMI to decide whether certain workarounds for buggy hardware and/or firmware need to be enabled.

ARM: 8663/1: wire up HWCAP/HWCAP2 feature bits to the CPU modalias
Wire up the generic support for exposing CPU feature bits via the modalias in /sys/device/system/cpu. This allows udev to automatically load modules for things like crypto algorithms that are implemented using optional instructions. Since it is non-trivial to transparantly support both HWCAP and HWCAP2 capabilities in the cpu_feature() macro (which allows a module's hwcap dependency and init routine to be declared using a single invocation of module_cpu_feature_match()), support only HWCAP2 for now, which covers the capabilities that are most likely to be useful in this manner. Module dependencies on HWCAP will need to be declared explicitly via a MODULE_DEVICE_TABLE(cpu, ...) declaration.

ARM: gemini: DT for the Cortina Gemini SoC platforms
This adds initial and compulsory device tree support to the Gemini ARMv4 platform. We are selecting a bunch of "absolute minimals" for getting a working system up with just device tree: - We select USE_OF for natural reasons or nothing works. - We select CLKSRC_OF and GEMINI_TIMER so we get timekeeping from the clocksource. - We select GPIO_GEMINI because these are used as irqchips, and for a generic driver it is not reasonable for those to have to select every possible irqchip in the world to work, the platform should simply provide the available irqchips. - We select a UART that can be exprected to work with SERIAL_OF_PLATFORM which is the name for an 8250 OF-probed serial port. - We select the syscon-based reset controller: it's not fun when "reboot" doesn't work because of Kconfig, so we just select POWER_RESET and POWER_RESET_SYSCON. - We perhaps a bit controversiallt select ARM_APPENDED_DTB, because this platform is using the ancient RedBoot, and can *NOT* be expected to upgrade its bootloaders. Appended device tree is simply how these devices have to work with device tree.

arch: add ARCH_HAS_SET_MEMORY config
Currently, there's no good way to test for the presence of set_memory_ro/rw/x/nx() helpers implemented by archs such as x86, arm, arm64 and s390. There's DEBUG_SET_MODULE_RONX and DEBUG_RODATA, however both don't really reflect that: set_memory_*() are also available even when DEBUG_SET_MODULE_RONX is turned off, and DEBUG_RODATA is set by parisc, but doesn't implement above functions. Thus, add ARCH_HAS_SET_MEMORY that is selected by mentioned archs, where generic code can test against this. This also allows later on to move DEBUG_SET_MODULE_RONX out of the arch specific Kconfig to define it only once depending on ARCH_HAS_SET_MEMORY.

ARM: Drop fixed 200 Hz timer requirement from Samsung platforms
All Samsung platforms, including the Exynos, are selecting HZ_FIXED with
200 Hz. Unfortunately in case of multiplatform image this affects also
other platforms when Exynos is enabled.
This looks like an very old legacy code, dating back to initial
upstreaming of S3C24xx. Probably it was required for s3c24xx timer
driver, which was removed in commit

ARM: SoC cleanups for v4.9
The cleanups for v4.9 are a little larger that usual, but thankfully that is almost exclusively due to removing a significant number of files that have become obsolete after the still ongoing conversion of old board files to devicetree. - for mach-omap2, which is still the largest platform in arch/arm/, the conversion to DT is finally complete after the Nokia N900 is now fully supported there, along with the omap3 LDP, and we can remove those two board files. If no regressions are found, another large cleanup for the platform will happen as a follow-up, removing dead code and restructuring the platform based on being DT-only. - In mach-imx, similar work is ongoing, but has not come that far. This time, we remove the obsolete board file for the i.MX1 generation, which like i.MX25, i.MX5, i.MX6, and i.MX7 is now DT-only. The remaining board files are for i.MX2 and i.MX3 machines based on old ARM926 or ARM1136 cores that should work with DT in principle. - realview has just been converted from board files to DT, and a lot of code gets removed in the process. This is the last ARM/Keil/Versatile derived platform that was still using board files, the other ones being integrator, versatile and vexpress. We can probably merge the remaining code into a single directory in the near future. - clps711x had completed the conversion in v4.8, but we accidentally left the files in place that should have been deleted then. Conflicts: two files deleted here have been modified upstream, the changes can be discarded. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIVAwUAV/guBGCrR//JCVInAQJoaQ/+N42zjmqDg6zO2JSs3q793AHskllT7kJo 2G36Afl3hOZqy2TFF8nq5Iv8/hb45+3bHBIlq+JrOq5Fep3wFVfT0d1HMQ8UG6+K jSMikItIZkOJdmjuZLEBzhjUFIEIpIrSuSY1Pej5Sy8zDzxT+n68gVqcm/qxa2w6 gPThdL69/XDo7JkF9TbYn0nrECey3ps9XnikNITWyQTrvCmlDVtGp6B+Cwi4cyvh FfJ690GAJU3/9op+xLomtEt1sli/+xJUdpH0IktfuNrc/2i96NsiUgPbqprIP6C6 rGRN40tDClYa1viRexZlZdkCd7nH9PC+VCC59FONYiY8WmpwtNPVZ8px4D/rv7AX GHDnqeVbzUK/CMxRsQC0bnvQnD/oDqkSkDD7ixzfUh2TQiJASXvuj1vOej5k06Vc KFkpjh1dSZkehkUp106F2Obm8Sh7nNoG2olzrlzlza97OuYxAEBungIn95vjYbUj IRrTQdKgv3gVVGXzHjH7TMr46MZLk6K4mHjDeuQr/NN8JyPH0uLTy6pjsdXRWCvO sIWVhyMohKMU2q5NeBWmY0OtDje93JchRVeKfRaQ3+YysPMUTBK5ZtI5GB9tsM14 7/GA7MO4FA0MZWW2E/GllQzgreaokUzTxBbhANzcEyjGh9OEx4gYaSF68PRy/HBa TlhH1PR3PNg= =WaLy -----END PGP SIGNATURE----- Merge tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC cleanups from Arnd Bergmann: "The cleanups for v4.9 are a little larger that usual, but thankfully that is almost exclusively due to removing a significant number of files that have become obsolete after the still ongoing conversion of old board files to devicetree. - for mach-omap2, which is still the largest platform in arch/arm/, the conversion to DT is finally complete after the Nokia N900 is now fully supported there, along with the omap3 LDP, and we can remove those two board files.

atomic64: no need for CONFIG_ARCH_HAS_ATOMIC64_DEC_IF_POSITIVE
This came to light when implementing native 64-bit atomics for ARCv2. The atomic64 self-test code uses CONFIG_ARCH_HAS_ATOMIC64_DEC_IF_POSITIVE to check whether atomic64_dec_if_positive() is available. It seems it was needed when not every arch defined it. However as of current code the Kconfig option seems needless - for CONFIG_GENERIC_ATOMIC64 it is auto-enabled in lib/Kconfig and a generic definition of API is present lib/atomic64.c - arches with native 64-bit atomics select it in arch/*/Kconfig and define the API in their headers So I see no point in keeping the Kconfig option Compile tested for: - blackfin (CONFIG_GENERIC_ATOMIC64) - x86 (!CONFIG_GENERIC_ATOMIC64) - ia64 Link: http://lkml.kernel.org/r/1473703083-8625-3-git-send-email-vgupta@synopsys.com Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Cc: Richard Henderson <rth@twiddle.net> Cc: Ivan Kokshaysky <ink@jurassic.park.msu.ru> Cc: Matt Turner <mattst88@gmail.com> Cc: Russell King <linux@armlinux.org.uk> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Will Deacon <will.deacon@arm.com> Cc: Ralf Baechle <ralf@linux-mips.org> Cc: "James E.J.

ARM: select PCI_DOMAINS config from ARCH_MULTIPLATFORM
PCI_DOMAINS config should be selected for any SoCs having more than a single PCIe controller. Without PCI_DOMAINS config, only one PCIe controller gets registered. Select PCI_DOMAINS in ARCH_MULTIPLATFORM if PCI is selected, since it doesn't harm even if a platform has a single PCIe port. Also remove PCI_DOMAINS being selected from other platform specific configs.

ARM: realview: imply device tree boot
This reduces the Kconfig for the RealView by assuming we are always booting from the device tree, and removing all the uses of CONFIG_REALVIEW_DT and replacing with CONFIG_ARCH_REALVIEW. Further: - Drop REALVIEW_HIGH_PHYS_OFFSET: we don't use this with device tree. - Drop the REALVIEW_EB_ARM11MP_REVB option: we now handle this by simply using another device tree. - Drop the PB1176 secure flash option: this is defined in the PB1176 device tree but marked as "disabled", so users who want to use it can simply enable it in the device tree and go hacking around.

ARM: 8560/1: errata: Workaround errata A12 825619 / A17 852421
The workaround for both errata is to set bit 24 in the diagnostic register. There are no known end-user bugs solved by fixing this errata, but the fix is trivial and it seems sane to apply it.

Note that applying this errata fixes deadlocks that are easy to reproduce with real world applications.

ARM: 8558/1: errata: Workaround errata A12 818325/852422 A17 852423
There are several similar errata on Cortex A12 and A17 that all have the same workaround: setting bit[12] of the Feature Register. Technically the list of errata are: - A12 818325: Execution of an UNPREDICTABLE STR or STM instruction might deadlock. Fixed in r0p1. - A12 852422: Execution of a sequence of instructions might lead to either a data corruption or a CPU deadlock. Not fixed in any A12s yet. - A17 852423: Execution of a sequence of instructions might lead to either a data corruption or a CPU deadlock. Not fixed in any A17s yet. Since A12 got renamed to A17 it seems likely that there won't be any future Cortex-A12 cores, so we'll enable for all Cortex-A12. For Cortex-A17 I believe that all known revisions are affected and that all knows revisions means <= r1p2. Presumably if a new A17 was released it would have this problem fixed. Note that in <https://patchwork.kernel.org/patch/4735341/> folks previously expressed opposition to this change because: A) It was thought to only apply to r0p0 and there were no known r0p0 boards supported in mainline. B) It was argued that such a workaround beloned in firmware. Now that this same fix solves other errata on real boards (like rk3288) point A) is addressed. Point B) is impossible to address on boards like rk3288. On rk3288 the firmware doesn't stay resident in RAM and isn't involved at all in the suspend/resume process nor in the SMP bringup process. That means that the most the firmware could do would be to set the bit on "core 0" and this bit would be lost at suspend/resume time. It is true that we could write a "generic" solution that saved the boot-time "core 0" value of this register and applied it at SMP bringup / resume time. However, since this register (described as the "Feature Register" in errata) appears to be undocumented (as far as I can tell) and is only modified for these errata, that "generic" solution seems questionably cleaner. The generic solution also won't fix existing users that haven't happened to do a FW update. Note that in ARM64 presumably PSCI will be universal and fixes like this will end up in ATF. Hopefully we are nearing the end of this style of errata workaround.

PCI/MSI: irqchip: Fix PCI_MSI dependencies
The PCI_MSI symbol is used inconsistently throughout the tree, with some drivers using 'select' and others using 'depends on', or using conditional selects. This keeps causing problems; the latest one is a result of ARCH_ALPINE using a 'select' statement to enable its platform-specific MSI driver without enabling MSI: warning: (ARCH_ALPINE) selects ALPINE_MSI which has unmet direct dependencies (PCI && PCI_MSI) drivers/irqchip/irq-alpine-msi.c:104:15: error: variable 'alpine_msix_domain_info' has initializer but incomplete type static struct msi_domain_info alpine_msix_domain_info = { ^~~~~~~~~~~~~~~ drivers/irqchip/irq-alpine-msi.c:105:2: error: unknown field 'flags' specified in initializer .flags = MSI_FLAG_USE_DEF_DOM_OPS | MSI_FLAG_USE_DEF_CHIP_OPS | ^ drivers/irqchip/irq-alpine-msi.c:105:11: error: 'MSI_FLAG_USE_DEF_DOM_OPS' undeclared here (not in a function) .flags = MSI_FLAG_USE_DEF_DOM_OPS | MSI_FLAG_USE_DEF_CHIP_OPS | ^~~~~~~~~~~~~~~~~~~~~~~~ There is little reason to enable PCI support for a platform that uses MSI but then leave MSI disabled at compile time. Select PCI_MSI from irqchips that implement MSI, and make PCI host bridges that use MSI on ARM depend on PCI_MSI_IRQ_DOMAIN. For all three architectures that support PCI_MSI_IRQ_DOMAIN (ARM, ARM64, X86), enable it by default whenever MSI is enabled.

GCC plugin infrastructure
This patch allows to build the whole kernel with GCC plugins. It was ported from grsecurity/PaX. The infrastructure supports building out-of-tree modules and building in a separate directory. Cross-compilation is supported too. Currently the x86, arm, arm64 and uml architectures enable plugins. The directory of the gcc plugins is scripts/gcc-plugins. You can use a file or a directory there. The plugins compile with these options: * -fno-rtti: gcc is compiled with this option so the plugins must use it too * -fno-exceptions: this is inherited from gcc too * -fasynchronous-unwind-tables: this is inherited from gcc too * -ggdb: it is useful for debugging a plugin (better backtrace on internal errors) * -Wno-narrowing: to suppress warnings from gcc headers (ipa-utils.h) * -Wno-unused-variable: to suppress warnings from gcc headers (gcc_version variable, plugin-version.h) The infrastructure introduces a new Makefile target called gcc-plugins. It supports all gcc versions from 4.5 to 6.0. The scripts/gcc-plugin.sh script chooses the proper host compiler (gcc-4.7 can be built by either gcc or g++). This script also checks the availability of the included headers in scripts/gcc-plugins/gcc-common.h. The gcc-common.h header contains frequently included headers for GCC plugins and it has a compatibility layer for the supported gcc versions. The gcc-generate-*-pass.h headers automatically generate the registration structures for GIMPLE, SIMPLE_IPA, IPA and RTL passes. Note that 'make clean' keeps the *.so files (only the distclean or mrproper targets clean all) because they are needed for out-of-tree modules. Based on work created by the PaX Team.

ARM: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB
This replaces: - "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can now be selected directly. - "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB is now selectable by everyone, so we need not declare our intent to select it. When ordering the symbols the following rationale was used: if the selects were in alphabetical order, I moved select GPIOLIB to be in alphabetical order, but if the selects were not maintained in alphabetical order, I just replaced "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

printk/nmi: generic solution for safe printk in NMI
printk() takes some locks and could not be used a safe way in NMI
context.
The chance of a deadlock is real especially when printing stacks from
all CPUs. This particular problem has been addressed on x86 by the

ARM: SoC platform updates for v4.7
We get support for three new 32-bit SoC platforms this time. The amount of changes in arch/arm for any of them is miniscule, as all the interesting code is in device driver subsystems (irqchip, clk, pinctrl, ...) these days. I'm listing them here, as the addition of the Kconfig statement is the main relevant milestone for a new platform. In each case, some drivers are are shared with existing platforms, while other drivers are added for v4.7 as well, or come in a later release. - The Aspeed platform is probably the most interesting one, this is what most whitebox servers use as their baseboard management controller. We get support for the very common ast2400 and ast2500 SoCs. The OpenBMC project focuses on this chip, and the LWN article about their ELC 2016 presentation at https://lwn.net/Articles/683320/ triggered the submission, but the code comes from IBM's OpenPOWER team rather than the team at Facebook. There are still a lot more drivers that need to get added over time, and I hope both teams can work together on that. - OXNAS is an old platform for Network Attached Storage devices from Oxford Semiconductor. There are models with ARM10 (!) and ARM11MPCore cores, but for now, we only support the original ARM9 based versions. The product lineup was subsequently part of PLX, Avago and now the new Broadcom Ltd. https://wiki.openwrt.org/doc/hardware/soc/soc.oxnas has some more information. - V2M-MPS2 is a prototyping platform from ARM for their Cortex-M cores and is related to the existing Realview / Versatile Express lineup, but without MMU. We now support various NOMMU platforms, so adding a new one is fairly straightforward. http://infocenter.arm.com/help/topic/com.arm.doc.100112_0100_03_en/ has detailed information about the platform. Other noteworthy updates: - Work on LPC32xx has resumed, and Vladimir Zapolskiy and Sylvain Lemieux are now maintaining the platform. This is an older ARM9 based platform from NXP (not Freescale), but it remains in use in embedded markets. - Kevin Hilman is now co-maintaining the Amlogic Meson platform for both 32-bit and 64-bit ARM, and started contributing some patches. - As is often the case, work on the OMAP platforms makes up the bulk of the actual SoC code changes in arch/arm, but there isn't a lot of that either. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIVAwUAVzuXX2CrR//JCVInAQLTghAA0f+2V2wC6HVBfDhT1YmhbAkPF1KzgLbB h30fN6BtIe9mE3kR69uWgwPSzn4hTKEQXoC9m6S+XClTn6MKPrbCEYDZl4ZwIER8 XDamxJV+6oTG+GKtKpHFkC4WPJkLthEuD34gr2xU8DFrU+y2Y5QNXi5wvSsBp8WS 6C/70HQEy35uSyOjbjVlPi0/UKoelVw9dCO7HZBOb9lTd88hC4Gx90KFwpq6Ievf L20VNgOESC2y6kRbuLNbhQVsbT2Ijyz9NccVM5owFEbHkXDxJ0vQVzrNM999DVjb CC2v0NZMLPNJQn2RvC172QBOsOERxIRkZdJHcifydl7i2QNpr8+/YSnS7OSx3dA/ 3ZmTLejaiGUXdTGEI9dHy77s+adwTzGsH+INKotQG8qwUXzCLuUWN3GGK+Qof5Rk jbsGAoZ7GQz1/7NdEOcGW6pxD4mllk3McKMzNlMmddRDUPhSUg3WXu0c1AWGzfA1 ulk6fQDaTUjvs7nokuozhguKz8OKrT6S7x/iES5tPbXLhuDqfnUdYiQ+7m2beRb5 L9S9KK95HXnKJAI9WLOELj1vCrfbCGjlwz8YVSrwPtwwzP/wbB1Ni6tmwLrxHbLk SGyJEMnPs3mARIPDwDysyOs+3OUSx04uYW6YTSh8XyKNIxTCflRxr/iM5YyYEMvt lXMrp1sh4hc= =5oFu -----END PGP SIGNATURE----- Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform updates from Arnd Bergmann: "We get support for three new 32-bit SoC platforms this time.

irqchip: Add LPC32xx interrupt controller driver
The change adds improved support of NXP LPC32xx MIC, SIC1 and SIC2 interrupt controllers. This is a list of new features in comparison to the legacy driver: * irq types are taken from device tree settings, no more need to hardcode them, * old driver is based on irq_domain_add_legacy, which causes problems with handling MIC hardware interrupt 0 produced by SIC1, * there is one driver for MIC, SIC1 and SIC2, no more need to handle them separately, e.g. have two separate handlers for SIC1 and SIC2, * the driver does not have any dependencies on hardcoded register offsets, * the driver is much simpler for maintenance, * SPARSE_IRQS option is supported. Legacy LPC32xx interrupt controller driver was broken since commit |

ARM: 8530/1: remove VIRT_TO_BUS
All drivers that are relevant for rpc or footbridge have stopped using virt_to_bus a while ago, so we can remove it and avoid some harmless randconfig warnings for drivers that we do not care about: drivers/atm/zatm.c: In function 'poll_rx': drivers/atm/zatm.c:401:18: warning: 'bus_to_virt' is deprecated [-Wdeprecated-declarations] skb = ((struct rx_buffer_head *) bus_to_virt(here[2]))->skb; FWIW, the remaining drivers using this are: ATM: firestream, zatm, ambassador, horizon ISDN: hisax/netjet V4L: STA2X11, zoran Net: Appletalk LTPC, Tulip DE4x5, Toshiba IrDA WAN: comtrol sv11, cosa, lanmedia, sealevel SCSI: DPT_I2O, buslogic VME: CA91C142 My best guess is that all of the above are so hopelessly obsolete that we are best off removing all of them form the kernel, but that can be done another time.

ARM: 8511/1: ARM64: kernel: PSCI: move PSCI idle management code to drivers/firmware
ARM64 PSCI kernel interfaces that initialize idle states and implement the suspend API to enter them are generic and can be shared with the ARM architecture. To achieve that goal, this patch moves ARM64 PSCI idle management code to drivers/firmware, so that the interface to initialize and enter idle states can actually be shared by ARM and ARM64 arches back-ends. The ARM generic CPUidle implementation also requires the definition of a cpuidle_ops section entry for the kernel to initialize the CPUidle operations at boot based on the enable-method (ie ARM64 has the statically initialized cpu_ops counterparts for that purpose); therefore this patch also adds the required section entry on CONFIG_ARM for PSCI so that the kernel can initialize the PSCI CPUidle back-end when PSCI is the probed enable-method. On ARM64 this patch provides no functional change.

ARM: 8510/1: rework ARM_CPU_SUSPEND dependencies
The code enabled by the ARM_CPU_SUSPEND config option is used by kernel subsystems for purposes that go beyond system suspend so its config entry should be augmented to take more default options into account and avoid forcing its selection to prevent dependencies override. To achieve this goal, this patch reworks the ARM_CPU_SUSPEND config entry and updates its default config value (by adding the BL_SWITCHER option to it) and its dependencies (ARCH_SUSPEND_POSSIBLE), so that the symbol is still selected by default by the subsystems requiring it and at the same time enforcing the dependencies correctly.

arm: lpc32xx: switch to common clock framework
The change switches NXP LPC32xx platforms to LPC32xx clock driver powered by common clock framework, this obsoletes mach-lpc32xx/clock.o legacy clock driver and thus it is removed. Legacy timer driver mach-lpc32xx/timer.o strictly depends on legacy clock support, but fortunately an existing LPC32xx clock source and clock event driver completely replaces it, and thus it can be removed as well. Noticeably platform UART driver directly operates on LPC32xx source control block registers, remove this dependency to avoid overlapping with common clock framework driver, also this guarantees that UART is working expectedly.

ARM: SoC multiplatform code changes for v4.5
This branch is the culmination of 5 years of effort to bring the ARMv6 and ARMv7 platforms together such that they can all be enabled and boot the same kernel. It has been a tremendous amount of cleanup and refactoring by a huge number of people, and creation of several new (and major) subsystems to better abstract out all the platform details in an appropriate manner. The bulk of this branch is a large patchset from Arnd that brings several of the more minor and older platforms we have closer to multiplatform support. Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview Much of this is moving around header files from old mach directories, but there are also some cleanup patches of debug_ll (lowlevel debug per-platform options) and other parts.

arm: mm: support ARCH_MMAP_RND_BITS
arm: arch_mmap_rnd() uses a hard-code value of 8 to generate the random offset for the mmap base address. This value represents a compromise between increased ASLR effectiveness and avoiding address-space fragmentation. Replace it with a Kconfig option, which is sensibly bounded, so that platform developers may choose where to place this compromise. Keep 8 as the minimum acceptable value.

libnvdimm for 4.5
1/ Media error handling: The 'badblocks' implementation that originated in md-raid is up-levelled to a generic capability of a block device. This initial implementation is limited to being consulted in the pmem block-i/o path. Later, 'badblocks' will be consulted when creating dax mappings. 2/ Raw block device dax: For virtualization and other cases that want large contiguous mappings of persistent memory, add the capability to dax-mmap a block device directly. 3/ Increased /dev/mem restrictions: Add an option to treat all io-memory as IORESOURCE_EXCLUSIVE, i.e. disable /dev/mem access while a driver is actively using an address range. This behavior is controlled via the new CONFIG_IO_STRICT_DEVMEM option and can be overridden by the existing "iomem=relaxed" kernel command line option. 4/ Miscellaneous fixes include a 'pfn'-device huge page alignment fix, block device shutdown crash fix, and other small libnvdimm fixes. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJWlrhjAAoJEB7SkWpmfYgCFbAQALKsQfFwT6JFS+zlPgiNpbqw 2VMNKEH0AfGYGj96mT02j2q+vSUmXLMIDMTsbe0sDdtwFZtQbFmhmryzPWUVppSu KGTlLPW8vuEhQVs91+UI3BQKkvpi0+tbR8hPOh9W6QhjpRT+lyHFKnsNR5HZy5wB K4/VMaT5ffd5/pXRTjkYiPQYTwWyfcvNjICj0YtqhPvOwS031m77JpFsWJ8HSpEX K99VlzNUPMXd1pYkHmFNXWw52fhRGNhwAEomLeKMdQfKms+KnbKp8BOSA0aCqU8E kpujQcilDXJwykFQZOFI3Z5Dxvrv8lxFTU8HRMBvo3ESzfTWjfqcvyjGOjDUcruw ihESFSJtdZzhrBiMnf9RRqSpMFJvAT8MVT6Q4D3mZUHCMPbUqFJsQjMPt9hEH3ho 4F0D2lesOCkubUKFTZmjMoDb+szuKbVhYK8TeFVVEhizinc/Aj0NKuazJqi+CXB/ xh0ER4ZxD8wvzqFFWvS5UvR1G9I5fr7+3jGRUrqGLHlSdeXP9dkEg28ao3QbWk3x 1dPOen6ZqQ9WJ/E7eGmXbVEz2R4Xd79hMXQzdQwmKDk/KbxRoAp7hyU8BslAyrBf HCdmVt+RAgrxZYfFRXuLhqwEBThJnNrgZA3qu74FUpkpFg6xRUu1bAYBiF7N+bFi 82b5UbMkveBTtkXjJoiR =7V5r -----END PGP SIGNATURE----- Merge tag 'libnvdimm-for-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm updates from Dan Williams: "The bulk of this has appeared in -next and independently received a build success notification from the kbuild robot.

Merge branch 'treewide/cleanup' into next/multiplatform
The realview multiplatform series has a trivial conflict with one of the treewide cleanups, let's just merge that in to avoid having to resolve this later. * treewide/cleanup: ARM: use "depends on" for SoC configs instead of "if" after prompt ARM/clocksource: use automatic DT probing for ux500 PRCMU ARM: use const and __initconst for smp_operations ARM: hisi: do not export smp_operations structures Conflicts: arch/arm/mach-integrator/Kconfig |

ARM: make default platform work for NOMMU
Moving ARCH_VERSATILE into ARCH_MULTIPLATFORM means that it no longer works as the default target for MMU-less kernels. While we might want to get that working again in the future, it's also a rather bad default, and it makes sense to make ARM_SINGLE_V7M the default because that is what realistically all NOMMU users on ARM are using, and it actually is what gets selected by default in the absence of versatile in the choice statement. Related to this, 'allnoconfig' kernels fail to link with the new default, as they do not include a machine record: arm-linux-gnueabi-ld: no machine record defined For ARCH_MULTIPLATFORM kernels, we avoid this error by using a default machine descriptor that works for all trivial platforms, like ARCH_VIRT. The same reasoning applies for ARM_SINGLE_V7M, as that can also boot with empty machine descriptors both on qemu and on real hardware, as long as all the drivers are present. We could also follow up with a patch to remove the existing machine descriptors for the ARMv7M platforms, the only callback pointer the four platforms contain today is the armv7m_restart handler and we can simply make that the default for v7M with an add-on patch.

ARM: 8477/1: runtime patch udiv/sdiv instructions into __aeabi_{u}idiv()
The ARM compiler inserts calls to __aeabi_idiv() and __aeabi_uidiv() when it needs to perform division on signed and unsigned integers. If a processor has support for the sdiv and udiv instructions, the kernel may overwrite the beginning of those functions with those instructions and a "bx lr" to get better performance. To ensure that those functions are aligned to a 32-bit word for easier patching (which might not always be the case in Thumb mode) and that the two patched instructions end up in the same cache line, a 8-byte alignment is enforced when ARM_PATCH_IDIV is selected. This was heavily inspired by a previous patch from Stephen Boyd.
