git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma Pull rdma DMA mapping updates from Doug Ledford: "Drop IB DMA mapping code and use core DMA code instead. Bart Van Assche noted that the ib DMA mapping code was significantly similar enough to the core DMA mapping code that with a few changes it was possible to remove the IB DMA mapping code entirely and switch the RDMA stack to use the core DMA mapping code. This resulted in a nice set of cleanups, but touched the entire tree and has been kept separate for that reason." * tag 'for-next-dma_ops' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (37 commits) IB/rxe, IB/rdmavt: Use dma_virt_ops instead of duplicating it IB/core: Remove ib_device.dma_device nvme-rdma: Switch from dma_device to dev.parent RDS: net: Switch from dma_device to dev.parent IB/srpt: Modify a debug statement IB/srp: Switch from dma_device to dev.parent IB/iser: Switch from dma_device to dev.parent IB/IPoIB: Switch from dma_device to dev.parent IB/rxe: Switch from dma_device to dev.parent IB/vmw_pvrdma: Switch from dma_device to dev.parent IB/usnic: Switch from dma_device to dev.parent IB/qib: Switch from dma_device to dev.parent IB/qedr: Switch from dma_device to dev.parent IB/ocrdma: Switch from dma_device to dev.parent IB/nes: Remove a superfluous assignment statement IB/mthca: Switch from dma_device to dev.parent IB/mlx5: Switch from dma_device to dev.parent IB/mlx4: Switch from dma_device to dev.parent IB/i40iw: Remove a superfluous assignment statement IB/hns: Switch from dma_device to dev.parent ...

2017-02-25platform/x86: intel_pmc_ipc: read s0ix residency APIShanth Murthy1-0/+6
This patch adds a new API to indicate S0ix residency in usec. It utilizes the PMC Global Control Registers (GCR) to read deep and shallow S0ix residency. PMC MMIO resources: o Lower 4kB: IPC1 (PMC inter-processor communication) interface o Upper 4kB: GCR (Global Control Registers) This enables the power management framework to take corrective actions when the platform fails to enter S0ix after kernel freeze as part of the suspend to idle flow. (echo freeze > /sys/power/state).

2017-02-25userfaultfd: non-cooperative: add event for memory unmapsMike Rapoport4-5/+5
When a non-cooperative userfaultfd monitor copies pages in the background, it may encounter regions that were already unmapped. Addition of UFFD_EVENT_UNMAP allows the uffd monitor to track precisely changes in the virtual memory layout. Since there might be different uffd contexts for the affected VMAs, we first should create a temporary representation for the unmap event for each uffd context and then notify them one by one to the appropriate userfault file descriptors. The event notification occurs after the mmap_sem has been released.

2017-02-25mm, x86: add support for PUD-sized transparent hugepagesMatthew Wilcox10-0/+251
The current transparent hugepage code only supports PMDs. This patch adds support for transparent use of PUDs with DAX. It does not include support for anonymous pages. x86 support code also added. Most of this patch simply parallels the work that was done for huge PMDs. The only major difference is how the new ->pud_entry method in mm_walk works. The ->pmd_entry method replaces the ->pte_entry method, whereas the ->pud_entry method works along with either ->pmd_entry or ->pte_entry. The pagewalk code takes care of locking the PUD before calling ->pud_walk, so handlers do not need to worry whether the PUD is stable.

Originally openrisc spec 0 specified that r0 would be wired to ground. This is no longer the case. r0 is not guaranteed to be 0 at init, so we need to initialize it to 0 before using it.

2017-02-24openrisc: Add optimized memcpy routineStafford Horne4-2/+128
The generic memcpy routine provided in kernel does only byte copies. Using word copies we can lower boot time and cycles spend in memcpy quite significantly. Booting on my de0 nano I see boot times go from 7.2 to 5.6 seconds. The avg cycles in memcpy during boot go from 6467 to 1887. I tested several algorithms (see code in previous patch mails) The implementations I tested and avg cycles: - Word Copies + Loop Unrolls + Non Aligned 1882 - Word Copies + Loop Unrolls 1887 - Word Copies 2441 - Byte Copies + Loop Unrolls 6467 - Byte Copies 7600 In the end I ended up going with Word Copies + Loop Unrolls as it provides best tradeoff between simplicity and boot speedups.

2017-02-24arm64/cpufeature: check correct field width when updating sys_valMark Rutland1-4/+10
When we're updating a register's sys_val, we use arm64_ftr_value() to find the new field value. We use cpuid_feature_extract_field() to find the new value, but this implicitly assumes a 4-bit field, so we may extract more bits than we mean to for fields like CTR_EL0.L1ip. This affects update_cpu_ftr_reg(), where we may extract erroneous values for ftr_cur and ftr_new. Depending on the additional bits extracted in either case, we may erroneously detect that the value is mismatched, and we'll try to compute a new safe value. Dependent on these extra bits and feature type, arm64_ftr_safe_value() may pessimistically select the always-safe value, or may erroneously choose either the extracted cur or new value as the safe option. The extra bits will subsequently be masked out in arm64_ftr_set_value(), so we may choose a higher value, yet write back a lower one. Fix this by passing the width down explicitly in arm64_ftr_value(), so we always extract the correct amount.

2017-02-24Revert "arm64: mm: set the contiguous bit for kernel mappings where appropriate"Mark Rutland1-30/+4
This reverts commit 0bfc445dec9dd8130d22c9f4476eed7598524129. When we change the permissions of regions mapped using contiguous entries, the architecture requires us to follow a Break-Before-Make strategy, breaking *all* associated entries before we can change any of the following properties from the entries: - presence of the contiguous bit - output address - attributes - permissiones Failure to do so can result in a number of problems (e.g. TLB conflict aborts and/or erroneous results from TLB lookups). See ARM DDI 0487A.k_iss10775, "Misprogramming of the Contiguous bit", page D4-1762. We do not take this into account when altering the permissions of kernel segments in mark_rodata_ro(), where we change the permissions of live contiguous entires one-by-one, leaving them transiently inconsistent. This has been observed to result in failures on some fast model configurations. Unfortunately, we cannot follow Break-Before-Make here as we'd have to unmap kernel text and data used to perform the sequence. For the timebeing, revert commit 0bfc445dec9dd813 so as to avoid issues resulting from this misuse of the contiguous bit.

2017-02-24objtool: Improve detection of BUG() and other dead endsJosh Poimboeuf1-0/+1
The BUG() macro's use of __builtin_unreachable() via the unreachable() macro tells gcc that the instruction is a dead end, and that it's safe to assume the current code path will not execute past the previous instruction. On x86, the BUG() macro is implemented with the 'ud2' instruction. When objtool's branch analysis sees that instruction, it knows the current code path has come to a dead end. Peter Zijlstra has been working on a patch to change the WARN macros to use 'ud2'. That patch will break objtool's assumption that 'ud2' is always a dead end. Generally it's best for objtool to avoid making those kinds of assumptions anyway. The more ignorant it is of kernel code internals, the better. So create a more generic way for objtool to detect dead ends by adding an annotation to the unreachable() macro. The annotation stores a pointer to the end of the unreachable code path in an '__unreachable' section. Objtool can read that section to find the dead ends.

2017-02-24s390/crypt: Add protected key AES moduleMartin Schwidefsky3-2/+633
This patch introduces a new in-kernel-crypto blockcipher called 'paes' which implements AES with protected keys. The paes blockcipher can be used similar to the aes blockcipher but uses secure key material to derive the working protected key and so offers an encryption implementation where never a clear key value is exposed in memory. The paes module is only available for the s390 platform providing a minimal hardware support of CPACF enabled with at least MSA level 3. Upon module initialization these requirements are checked. Includes additional contribution from Harald Freudenberger. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform updates from Arnd Bergmann: "In the SoC branch we normally collect classic arch/arm/mach-* contents, i.e. C code changes for SoC platforms. This release cycle the diffstat is quite nice, in that we're removing 3x the amount of code that's being added. The main reason for this is that there's a removal of camera drivers for Freescale i.MX chips (driver was removed so the device registration isn't needed any more). There's also removal of display initialization code for OMAP that is no longer needed. The rest are mostly minor tweaks and cleanups; constification on Samsung platforms, cleanup of ux500 platform data, purge of other unused platform data/device seutp on i.MX and other good stuff. New SoC support this cycle is for two Allwinner platforms, H2+ and V3s" * tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (55 commits) ARM: ux500: remove deleted file from Makefile ARM: ep93xx: Disable TS-72xx watchdog before uncompressing ARM: ux500: cut some platform data MAINTAINERS: Update for the current location of the bcm2835 tree.
