drivers/perf: arm_pmu: Request PMU SPIs with IRQF_PER_CPU
Since the PMU register interface is banked per CPU, CPU PMU interrrupts
cannot be handled by a CPU other than the one with the PMU asserting the
interrupt. This means that migrating PMU SPIs, as we do during a CPU
hotplug operation doesn't make any sense and can lead to the IRQ being
disabled entirely if we route a spurious IRQ to the new affinity target.
This has been observed in practice on AMD Seattle, where CPUs on the
non-boot cluster appear to take a spurious PMU IRQ when coming online,
which is routed to CPU0 where it cannot be handled.
This patch passes IRQF_PERCPU for PMU SPIs and forcefully sets their
affinity prior to requesting them, ensuring that they cannot
be migrated during hotplug events. This interacts badly with the DB8500
erratum workaround that ping-pongs the interrupt affinity from the handler,
so we avoid passing IRQF_PERCPU in that case by allowing the IRQ flags
to be overridden in the platdata.

ARM: 8687/1: signal: Fix unparseable iwmmxt_sigframe in uc_regspace[]
In kernels with CONFIG_IWMMXT=y running on non-iWMMXt hardware, the signal frame can be left partially uninitialised in such a way that userspace cannot parse uc_regspace[] safely. In particular, this means that the VFP registers cannot be located reliably in the signal frame when a multi_v7_defconfig kernel is run on the majority of platforms. The cause is that the uc_regspace[] is laid out statically based on the kernel config, but the decision of whether to save/restore the iWMMXt registers must be a runtime decision. To minimise breakage of software that may assume a fixed layout, this patch emits a dummy block of the same size as iwmmxt_sigframe, for non-iWMMXt threads. However, the magic and size of this block are now filled in to help parsers skip over it. A new DUMMY_MAGIC is defined for this purpose. It is probably legitimate (if non-portable) for userspace to manufacture its own sigframe for sigreturn, and there is no obvious reason why userspace should be required to insert a DUMMY_MAGIC block when running on non-iWMMXt hardware, when omitting it has worked just fine forever in other configurations. So in this case, sigreturn does not require this block to be present.

preserve_iwmmxt_context() and restore_iwmmxt_context() lack __user accessors on their arguments pointing to the user signal frame.

dma-coherent: introduce interface for default DMA pool
Christoph noticed [1] that default DMA pool in current form overload the DMA coherent infrastructure. In reply, Robin suggested [2] to split the per-device vs. global pool interfaces, so allocation/release from default DMA pool is driven by dma ops implementation. This patch implements Robin's idea and provide interface to allocate/release/mmap the default (aka global) DMA pool. To make it clear that existing *_from_coherent routines work on per-device pool rename them to *_from_dev_coherent.

ARM: kexec: fix failure to boot crash kernel
When kexec was converted to DTB, the dtb address was passed between machine_kexec_prepare() and machine_kexec() using a static variable. This is bad news if you load a crash kernel followed by a normal kernel or vice versa - the last loaded kernel overwrites the dtb address. This can result in kexec failures, as (eg) we try to boot the crash kernel with the last loaded dtb. For example, with: the crash kernel fails to find the dtb. Avoid this by defining a kimage architecture structure, and store the address to be passed in r2 there, which will either be the ATAGs or the dtb blob. Fixes: |

ARM: HP Jornada 7XX: move inline before return type
Convert 'u8 inline' to 'inline u8' to be the same style used by the rest of the kernel. Miscellanea: jornada_ssp_reverse is an odd function. It is declared inline but is also EXPORT_SYMBOL. It is also apparently only used by jornada720_ssp.c Likely the EXPORT_SYMBOL could be removed and the function converted to static. The addition of static and removal of EXPORT_SYMBOL was not done.

arm: move ELF_ET_DYN_BASE to 4MB
Now that explicitly executed loaders are loaded in the mmap region, we have more freedom to decide where we position PIE binaries in the address space to avoid possible collisions with mmap or stack regions. 4MB is chosen here mainly to have parity with x86, where this is the traditional minimum load location, likely to avoid historically requiring a 4MB page table entry when only a portion of the first 4MB would be used (since the NULL address is avoided). For ARM the position could be 0x8000, the standard ET_EXEC load address, but that is needlessly close to the NULL address, and anyone running PIE on 32-bit ARM will have an MMU, so the tight mapping is not needed.

ARM: fix rd_size declaration
The global variable 'rd_size' is declared as 'int' in source file arch/arm/kernel/atags_parse.c and as 'unsigned long' in drivers/block/brd.c. Fix this inconsistency. Additionally, remove the declarations of rd_image_start, rd_prompt and rd_doload from parse_tag_ramdisk() since these duplicate existing declarations in <linux/initrd.h>.

This is the bulk of GPIO changes for the v4.13 series:
Core:
- Export add/remove for lookup tables so that modules can export GPIO
descriptor tables.
- Handle GPIO sleep states: it is now possible to flag that a GPIO line
may loose its state during suspend/resume of the system to save
power. This is used in the Wolfson Micro Arizona driver.
- ACPI-based GPIO was tightened up a lot around the edges.
- Use bitmap_fill() to speed up a loop.
New drivers:
- Exar XRA1403 SPI-based GPIO.
- MVEBU driver now supports Armada 7K and 8K.
- LP87565 PMIC GPIO.
- Renesas R-CAR R8A7743 (RZ/G1M).
- The new IOT2040 8250 serial/GPIO also comes in through this
changeset.
Substantial driver changes:
- Seriously fix the Exar 8250 GPIO portions to work.
- The MCP23S08 was moved out to a pin control driver.
- Convert MEVEBU to use regmap for register access.
- Drop Vulcan support from the Broadcom driver.
- Serious cleanup and improvement of the mockup driver, giving us a
better test coverage.
Misc:
- Lots of janitorial clean up.
- A bunch of documentation fixes.

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.13 series.
Some administrativa:
I have a slew of 8250 serial patches and the new IOT2040 serial+GPIO
driver coming in through this tree, along with a whole bunch of Exar
8250 fixes. These are ACKed by Greg and also hit drivers/platform/*
where they are ACKed by Andy Shevchenko.
Speaking about drivers/platform/* there is also a bunch of ACPI stuff
coming through that route, again ACKed by Andy.
The MCP23S08 changes are coming in here as well. You already have the
commits in your tree, so this is just a result of sharing an immutable
branch between pin control and GPIO.

This is the first pull request for the new dma-mapping subsystem
In this new subsystem we'll try to properly maintain all the generic
code related to dma-mapping, and will further consolidate arch code
into common helpers.
This pull request contains:
- removal of the DMA_ERROR_CODE macro, replacing it with calls
to ->mapping_error so that the dma_map_ops instances are
more self contained and can be shared across architectures (me)
- removal of the ->set_dma_mask method, which duplicates the
->dma_capable one in terms of functionality, but requires more
duplicate code.
- various updates for the coherent dma pool and related arm code
(Vladimir)
- various smaller cleanups (me)

This is the big bulk of pin control changes for the v4.13 series:
Core:
- The documentation is moved over to RST.
- We now have agreed bindings for enabling input and output
buffers without actually enabling input and/or output on a
pin. We are chiseling out some details of pin control
electronics.
New drivers:
- ZTE ZX
- Renesas RZA1
- MIPS Ingenic JZ47xx: also switch over existing drivers in the
tree to use this pin controller and consolidate earlier
spread out code.
- Microschip MCP23S08: this driver is migrated from the GPIO
subsystem and totally rewritten to use proper pin control.
All users are switched over.
New subdrivers:
- Renesas R8A7743 and R8A7745.
- Allwinner Sunxi A83T R_PIO.
- Marvell MVEBU Armada CP110 and AP806.
- Intel Cannon Lake PCH.
- Qualcomm IPQ8074.
Notable improvements:
- IRQ support on the Marvell MVEBU Armada 37xx.
- Meson driver supports HDMI CEC, AO, I2S, SPDIF and PWM.
- Rockchip driver now supports iomux-route switching for
RK3228, RK3328 and RK3399.
- Rockchip A10 and A20 are merged into a single driver.
- STM32 has improved GPIO support.
- Samsung Exynos drivers are split per ARMv7 and ARMv8.
- Marvell MVEBU is converted to use regmap for register
access.
Maintenance:
- Several Renesas SH-PFC refactorings and updates.
- Serious code size cut for Mediatek MT7623.
- Misc janitorial and MAINTAINERS fixes.

ARM: SoC defconfig updates

ARM: Device-tree updates
Device-tree continues to see lots of updates. The majority of patches
here are smaller changes for new hardware on existing platforms, and
there are a few larger changes worth pointing out.
New machines:
- The new Action Semi S500 platform is added along with initial
support for the LeMaker Guitar board.
- STM32 gains support for three new boards: stm32h743-disco,
stm32f746-disco, and stm32f769-disco, along with new device
support for the existing stm32f429 boards.
- Renesas adds two new boards, the tiny GR-Peach based on RZ/A1H
with 10MB on-chip SRAM, and the iWave G20D-Q7 System-on-Module
plus board.
- On Marvell "mvebu", we gain support for the Linksys WRT3200ACM
wireless router.
- For NXP i.MX, we gain support for the Gateworks Ventana GW5600
and the Technexion Pico i.MX7D single-board computers.
- The BeagleBone Blue is added for OMAP, it's the latest variation
of the popular Beaglebone Black single-board computer.
- The Allwinner based Lichee Pi Zero and NanoPi M1 Plus boards
are added, these are the latest variations of a seemingly endless
supply of similar single-board computers.
Other updates:
- Linus Walleij improves support for the "Faraday" based SoC platforms
from various SoC makers (Moxart, Aspeed, Gemini)
- The ARM Mali GPU is now describe on Rockchips SoCs
- Mediatek MT7623 is extended significantly, making it much
more useful.
- Lots of individual updates on Renesas, OMAP, Rockchips, Broadcom,
Allwinner, Qualcomm, iMX
- For Amlogic, the clock support is extended a lot on meson8b.
- We now build the devicetree file for the Raspberry Pi 3 on 32-bit
ARM, in addition to the existing ARM64 support, to help users
wanting to run a 32-bit system on it.

ARM: SoC non-urgent fixes for merge window
Smaller patches that didn't seem to find a home in other branches, and
low-priority fixes from late in the merge window.
- Lee Jones retires as bcm2835 (raspberry pi) co-maintainer.
- A couple of bugfixes for the ARM CCN bus driver that were
regarded not important enough
- minor device tree fixes for the Renesas and Marvell platforms,
that came a little late or did not justify have another
pull request after the last -rc.

USB/PHY patches for 4.13-rc1
Here is the big patchset of USB and PHY driver updates for 4.13-rc1. On the PHY side, they decided to move files around to "make things easier" in their tree. Hopefully that wasn't a mistake, but in linux-next testing, we haven't had any reported problems. There's the usual set of gadget and xhci and musb updates in here as well, along with a number of smaller updates for a raft of different USB drivers. Full details in the shortlog, nothing really major. All of these have been in linux-next for a while with no reported issues.

Merge branch 'smp-hotplug-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull SMP hotplug updates from Thomas Gleixner: "This update is primarily a cleanup of the CPU hotplug locking code. The hotplug locking mechanism is an open coded RWSEM, which allows recursive locking. The main problem with that is the recursive nature as it evades the full lockdep coverage and hides potential deadlocks. The rework replaces the open coded RWSEM with a percpu RWSEM and establishes full lockdep coverage that way. The bulk of the changes fix up recursive locking issues and address the now fully reported potential deadlocks all over the place. Some of these deadlocks have been observed in the RT tree, but on mainline the probability was low enough to hide them away." * 'smp-hotplug-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (37 commits) cpu/hotplug: Constify attribute_group structures powerpc: Only obtain cpu_hotplug_lock if called by rtasd ARM/hw_breakpoint: Fix possible recursive locking for arch_hw_breakpoint_init cpu/hotplug: Remove unused check_for_tasks() function perf/core: Don't release cred_guard_mutex if not taken cpuhotplug: Link lock stacks for hotplug callbacks acpi/processor: Prevent cpu hotplug deadlock sched: Provide is_percpu_thread() helper cpu/hotplug: Convert hotplug locking to percpu rwsem s390: Prevent hotplug rwsem recursion arm: Prevent hotplug rwsem recursion arm64: Prevent cpu hotplug rwsem recursion kprobes: Cure hotplug lock ordering issues jump_label: Reorder hotplug lock and jump_label_lock perf/tracing/cpuhotplug: Fix locking order ACPI/processor: Use cpu_hotplug_disable() instead of get_online_cpus() PCI: Replace the racy recursion prevention PCI: Use cpu_hotplug_disable() instead of get_online_cpus() perf/x86/intel: Drop get_online_cpus() in intel_snb_check_microcode() x86/perf: Drop EXPORT of perf_check_microcode ... |
