ARM: SoC support for Tegra platforms for v4.5
Here's a single-SoC topic branch that we've staged separately. Mainly because it was hard to sort the branch contents in a way that fit our existing branches due to some refactorings. The code has been in -next for quite a while, but we staged it in arm-soc a bit late, which is why we've kept it separate from the other updates and are sending it separately here. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJWoqsGAAoJEIwa5zzehBx3/F4QAJo4FEU+KTOhUggDV+KPn9ZD Re1SAKTpKo9elMdDdTZZObHYPf+RXqun50C4pQiSVfyDm9syZaxtWjjZvshwsATq 178fNN+0C/7aenj8Zpq/NrLwBl1N51cSdc1ii3TcN/OA5XDgpmGJTdqMziDiXAkd Nt847qSEhIvAfOtcZR2drk2wBKGCTA/NpGU3HCryPAlO7RnAbJY4Ywj0bU01Lc9y bSJYh1SPaa1PdDCBJjtbk6L8iGl39K5oy0e6ehECEviLBVtWIL0zqh101XGbPVtv vtpVJ40NciiHknCBEiJkYiY9b7BNZYMeuwLarqk7TxyW4Vm5Rl5CFkEot0X/b70J XSxca6KGLzSgmCYDzJtLgtmyBUDoGqNwiPnNVIjrGIt9uOlWeHGb7TUKjBZaJr7G nXiKKU17zhb28hEo8JjIGcuFcOGlwlBhoOKhOYePiXX/iA03M8SEZg3XXyYMiaVz j9PcfOQptc7CyCAyiUQW36cZc1vQlnNxpiZstF0QsJ+Poe1kPlJIVpOarrfFdvh5 wJrS4L5YoIzb5robsNLNJ6XXiRnqvxgO6dEdA3RoI1bMaFsXVRCb03EoxVYqS4RF o+4h0KYQ8gPmAhA/ii/IDHps51TCCDOolAyWLfmYlqXu76IjOlC1LTYxi8RAGZNL xExyC0A3YDfONv6mx07R =LG3u -----END PGP SIGNATURE----- Merge tag 'armsoc-tegra' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC support for Tegra platforms from Olof Johansson: "Here's a single-SoC topic branch that we've staged separately.

ARM: SoC driver updates for v4.5
Driver updates for ARM SoCs. Some for SoC-family code under drivers/soc,
but also some other driver updates that don't belong anywhere else. We also
bring in the drivers/reset code through arm-soc.
Some of the larger updates:
- Qualcomm support for SMEM, SMSM, SMP2P. All used to communicate with other
parts of the chip/board on these platforms, all proprietary protocols that
don't fit into other subsystems and live in drivers/soc for now.
- System bus driver for UniPhier
- Driver for the TI Wakeup M3 IPC device
- Power management for Raspberry PI
+ Again a bunch of other smaller updates and patches.

arm64: bpf: add extra pass to handle faulty codegen
Code generation functions in arch/arm64/kernel/insn.c previously BUG_ON invalid parameters. Following change of that behavior, now we need to handle the error case where AARCH64_BREAK_FAULT is returned. Instead of error-handling on every emit() in JIT, we add a new validation pass at the end of JIT compilation. There's no point in running JITed code at run-time only to trap due to AARCH64_BREAK_FAULT. Instead, we drop this failed JIT compilation and allow the system to gracefully fallback on the BPF interpreter.

arm64: insn: remove BUG_ON from codegen
During code generation, we used to BUG_ON unknown/unsupported encoding or invalid parameters. Instead, now we report these as errors and simply return the instruction AARCH64_BREAK_FAULT. Users of these codegen helpers should check for and handle this failure condition as appropriate. Otherwise, unhandled codegen failure will result in trapping at run-time due to AARCH64_BREAK_FAULT, which is arguably better than a BUG_ON.

kvm: rename pfn_t to kvm_pfn_t
To date, we have implemented two I/O usage models for persistent memory, PMEM (a persistent "ram disk") and DAX (mmap persistent memory into userspace). This series adds a third, DAX-GUP, that allows DAX mappings to be the target of direct-i/o. It allows userspace to coordinate DMA/RDMA from/to persistent memory. The implementation leverages the ZONE_DEVICE mm-zone that went into 4.3-rc1 (also discussed at kernel summit) to flag pages that are owned and dynamically mapped by a device driver. The pmem driver, after mapping a persistent memory range into the system memmap via devm_memremap_pages(), arranges for DAX to distinguish pfn-only versus page-backed pmem-pfns via flags in the new pfn_t type. The DAX code, upon seeing a PFN_DEV+PFN_MAP flagged pfn, flags the resulting pte(s) inserted into the process page tables with a new _PAGE_DEVMAP flag. Later, when get_user_pages() is walking ptes it keys off _PAGE_DEVMAP to pin the device hosting the page range active. Finally, get_page() and put_page() are modified to take references against the device driver established page mapping. Finally, this need for "struct page" for persistent memory requires memory capacity to store the memmap array. Given the memmap array for a large pool of persistent may exhaust available DRAM introduce a mechanism to allocate the memmap from persistent memory. The new "struct vmem_altmap *" parameter to devm_memremap_pages() enables arch_add_memory() to use reserved pmem capacity rather than the page allocator. This patch (of 18): The core has developed a need for a "pfn_t" type [1]. Move the existing pfn_t in KVM to kvm_pfn_t [2].

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.

arm64: head.S: use memset to clear BSS
Currently we use an open-coded memzero to clear the BSS. As it is a trivial implementation, it is sub-optimal. Our optimised memset doesn't use the stack, is position-independent, and for the memzero case can use of DC ZVA to clear large blocks efficiently. In __mmap_switched the MMU is on and there are no live caller-saved registers, so we can safely call an uninstrumented memset. This patch changes __mmap_switched to use memset when clearing the BSS. We use the __pi_memset alias so as to avoid any instrumentation in all kernel configurations.

arm64: entry: remove pointless SPSR mode check
In work_pending, we may skip work if the stacked SPSR value represents anything other than an EL0 context. We then immediately invoke the kernel_exit 0 macro as part of ret_to_user, assuming a return to EL0. This is somewhat confusing. We use work_pending as part of the ret_to_user/ret_fast_syscall state machine. We only use ret_fast_syscall in the return from an SVC issued from EL0. We use ret_to_user for return from EL0 exception handlers and also for return from ret_from_fork in the case the task was not a kernel thread (i.e. it is a user task). Thus in all cases the stacked SPSR value must represent an EL0 context, and the check is redundant. This patch removes it, along with the now unused no_work_pending label.

arm64: mm: move pgd_cache initialisation to pgtable_cache_init
Initialising the suppport for EFI runtime services requires us to allocate a pgd off the back of an early_initcall. On systems where the PGD_SIZE is smaller than PAGE_SIZE (e.g. 64k pages and 48-bit VA), the pgd_cache isn't initialised at this stage, and we panic with a NULL dereference during boot: Unable to handle kernel NULL pointer dereference at virtual address 00000000 __create_mapping.isra.5+0x84/0x350 create_pgd_mapping+0x20/0x28 efi_create_mapping+0x5c/0x6c arm_enable_runtime_services+0x154/0x1e4 do_one_initcall+0x8c/0x190 kernel_init_freeable+0x84/0x1ec kernel_init+0x10/0xe0 ret_from_fork+0x10/0x50 This patch fixes the problem by initialising the pgd_cache earlier, in the pgtable_cache_init callback, which sounds suspiciously like what it was intended for.

arm64: module: fix relocation of movz instruction with negative immediate
The test whether a movz instruction with a signed immediate should be turned into a movn instruction (i.e., when the immediate is negative) is flawed, since the value of imm is always positive. Also, the subsequent bounds check is incorrect since the limit update never executes, due to the fact that the imm_type comparison will always be false for negative signed immediates. Let's fix this by performing the sign test on sval directly, and replacing the bounds check with a simple comparison against U16_MAX.
