      Pull arm64 updates from Will Deacon:
       "Nothing particularly stands out here, probably because people were
        tied up with spectre/meltdown stuff last time around. Still, the main
        pieces are:
      
         - Rework of our CPU features framework so that we can whitelist CPUs
           that don't require kpti even in a heterogeneous system
      
         - Support for the IDC/DIC architecture extensions, which allow us to
           elide instruction and data cache maintenance when writing out
           instructions
      
         - Removal of the large memory model which resulted in suboptimal
           codegen by the compiler and increased the use of literal pools,
           which could potentially be used as ROP gadgets since they are
           mapped as executable
      
         - Rework of forced signal delivery so that the siginfo_t is
           well-formed and handling of show_unhandled_signals is consolidated
           and made consistent between different fault types
      
         - More siginfo cleanup based on the initial patches from Eric
           Biederman
      
         - Workaround for Cortex-A55 erratum #1024718
      
         - Some small ACPI IORT updates and cleanups from Lorenzo Pieralisi
      
         - Misc cleanups and non-critical fixes"

      Pull time(r) updates from Thomas Gleixner:
       "A small set of updates for timers and timekeeping:
      
         - The most interesting change is the consolidation of clock MONOTONIC
           and clock BOOTTIME.
      
           Clock MONOTONIC behaves now exactly like clock BOOTTIME and does
           not longer ignore the time spent in suspend. A new clock
           MONOTONIC_ACTIVE is provived which behaves like clock MONOTONIC in
           kernels before this change. This allows applications to
           programmatically check for the clock MONOTONIC behaviour.
      
           As discussed in the review thread, this has the potential of
           breaking user space and we might have to revert this. Knock on wood
           that we can avoid that exercise.
      
         - Updates to the NTP mechanism to improve accuracy
      
         - A new kernel internal data structure to aid the ongoing Y2038 work.
      
         - Cleanups and simplifications of the clocksource code.
      
         - Make the alarmtimer code play nicely with debugobjects"

       "There are a several user visible changes, the rest is mostly invisible
        and continues to clean up the whole code base.
      
        User visible changes:
         - new mount option nossd_spread (pair for ssd_spread)
      
         - mount option subvolid will detect junk after the number and fail
           the mount
      
         - add message after cancelled device replace
      
         - direct module dependency on libcrc32, removed own crc wrappers
      
         - removed user space transaction ioctls
      
         - use lighter locking when reading /proc/self/mounts, RCU instead of
           mutex to avoid unnecessary contention
      
        Enhancements:
         - skip writeback of last page when truncating file to same size
      
         - send: do not issue unnecessary truncate operations
      
         - mount option token specifiers: use %u for unsigned values, more
           validation
      
         - selftests: more tree block validations
      
        qgroups:
         - preparatory work for splitting reservation types for data and
           metadata, this should allow for more accurate tracking and fix some
           issues with underflows or do further enhancements
      
         - split metadata reservations for started and joined transaction so
           they do not get mixed up and are accounted correctly at commit time
      
         - with the above, it's possible to revert patch that potentially
           deadlocks when trying to make more space by explicitly committing
           when the quota limit is hit
      
         - fix root item corruption when multiple same source snapshots are
           created with quota enabled
      
        RAID56:
         - make sure target is identical to source when raid56 rebuild fails
           after dev-replace
      
         - faster rebuild during scrub, batch by stripes and not
           block-by-block
      
         - make more use of cached data when rebuilding from a missing device

       "Here's the first round of fixes for XFS for 4.17.
      
        The biggest new features this time around are the addition of lazytime
        support, further enhancement of the on-disk inode metadata verifiers,
        and a patch to smooth over some of the AGFL padding problems that have
        intermittently plagued users since 4.5. I forsee sending a second pull
        request next week with further bug fixes and speedups in the online
        scrub code and elsewhere.
      
        This series has been run through a full xfstests run over the weekend
        and through a quick xfstests run against this morning's master, with
        no major failures reported.
      
        Summary of changes for this release:
      
         - Various cleanups and code fixes
      
         - Implement lazytime as a mount option
      
         - Convert various on-disk metadata checks from asserts to -EFSCORRUPTED
      
         - Fix accounting problems with the rmap per-ag reservations
      
         - Refactorings and cleanups for xfs_log_force
      
         - Various bugfixes for the reflink code
      
         - Work around v5 AGFL padding problems to prevent fs shutdowns
      
         - Establish inode fork verifiers to inspect on-disk metadata
           correctness

      openrisc: Set CONFIG_MULTI_IRQ_HANDLER · 83fbdf1c
      Palmer Dabbelt authored
      arm has an optional MULTI_IRQ_HANDLER, which openrisc copied but didn't
      make optional.  The multi irq handler infrastructure has been copied to
      generic code selectable with a new config symbol. That symbol can be
      selected by randconfig builds and can cause build breakage.
      
      Introduce CONFIG_MULTI_IRQ_HANDLER as an intermediate step which prevents
      the core config symbol from being selected. The openrisc local config
      symbol will be removed once openrisc gets converted to the generic code.

      genirq: Make GENERIC_IRQ_MULTI_HANDLER depend on !MULTI_IRQ_HANDLER · d6f73825
      Palmer Dabbelt authored
      These config switches enable the same code in the core and the not yet
      converted architecture code. They can be selected both by randconfig builds
      and cause linker error because the same symbols are defined twice.
      
      Make the new GENERIC_IRQ_MULTI_HANDLER depend on !MULTI_IRQ_HANDLER to
      prevent that. The dependency will be removed once all architectures are
      converted over.

      Linus Torvalds authored
      Merge branch 'userns-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
      
      Pull namespace updates from Eric Biederman:
       "There was a lot of work this cycle fixing bugs that were discovered
        after the merge window and getting everything ready where we can
        reasonably support fully unprivileged fuse. The bug fixes you already
        have and much of the unprivileged fuse work is coming in via other
        trees.
      
        Still left for fully unprivileged fuse is figuring out how to cleanly
        handle .set_acl and .get_acl in the legacy case, and properly handling
        of evm xattrs on unprivileged mounts.
      
        Included in the tree is a cleanup from Alexely that replaced a linked
        list with a statically allocated fix sized array for the pid caches,
        which simplifies and speeds things up.
      
        Then there is are some cleanups and fixes for the ipc namespace. The
        motivation was that in reviewing other code it was discovered that
        access ipc objects from different pid namespaces recorded pids in such
        a way that when asked the wrong pids were returned. In the worst case
        there has been a measured 30% performance impact for sysvipc
        semaphores. Other test cases showed no measurable performance impact.
        Manfred Spraul and Davidlohr Bueso who tend to work on sysvipc
        performance both gave the nod that this is good enough.
      
        Casey Schaufler and James Morris have given their approval to the LSM
        side of the changes.
      
        I simplified the types and the code dealing with sysvipc to pass just
        kern_ipc_perm for all three types of ipc. Which reduced the header
        dependencies throughout the kernel and simplified the lsm code.
      
        Which let me work on the pid fixes without having to worry about
        trivial changes causing complete kernel recompiles"
      
      * 'userns-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace:

      Pull sparc updates from David Miller:
      
       1) Add support for ADI (Application Data Integrity) found in more
          recent sparc64 cpus. Essentially this is keyed based access to
          virtual memory, and if the key encoded in the virual address is
          wrong you get a trap.
      
          The mm changes were reviewed by Andrew Morton and others.
      
          Work by Khalid Aziz.
      
       2) Validate DAX completion index range properly, from Rob Gardner.
      
       3) Add proper Kconfig deps for DAX driver. From Guenter Roeck.

        depending on the current configuration, for example, and event

        the TAD, however.
      
        In addition to that the ACPI battery driver is improved to handle
        battery thresholds on ThinkPads, among other things, some bugs are

      Linus Torvalds authored
      Pull removal of in-kernel calls to syscalls from Dominik Brodowski:
       "System calls are interaction points between userspace and the kernel.
        Therefore, system call functions such as sys_xyzzy() or
        compat_sys_xyzzy() should only be called from userspace via the
        syscall table, but not from elsewhere in the kernel.
      
        At least on 64-bit x86, it will likely be a hard requirement from
        v4.17 onwards to not call system call functions in the kernel: It is
        better to use use a different calling convention for system calls
        there, where struct pt_regs is decoded on-the-fly in a syscall wrapper
        which then hands processing over to the actual syscall function. This
        means that only those parameters which are actually needed for a
        specific syscall are passed on during syscall entry, instead of
        filling in six CPU registers with random user space content all the
        time (which may cause serious trouble down the call chain). Those
        x86-specific patches will be pushed through the x86 tree in the near
        future.
      
        Moreover, rules on how data may be accessed may differ between kernel
        data and user data. This is another reason why calling sys_xyzzy() is
        generally a bad idea, and -- at most -- acceptable in arch-specific
        code.
      
        This patchset removes all in-kernel calls to syscall functions in the
        kernel with the exception of arch/. On top of this, it cleans up the
        three places where many syscalls are referenced or prototyped, namely
        kernel/sys_ni.c, include/linux/syscalls.h and include/linux/compat.h"

      bitmap: fix memset optimization on big-endian systems · 21035965
      Omar Sandoval authored
      Commit 2a98dc02 ("include/linux/bitmap.h: turn bitmap_set and
      bitmap_clear into memset when possible") introduced an optimization to
      bitmap_{set,clear}() which uses memset() when the start and length are
      constants aligned to a byte.
      
      This is wrong on big-endian systems; our bitmaps are arrays of unsigned
      long, so bit n is not at byte n / 8 in memory.  This was caught by the
      Btrfs selftests, but the bitmap selftests also fail when run on a
      big-endian machine.
      
      We can still use memset if the start and length are aligned to an
      unsigned long, so do that on big-endian.  The same problem applies to
      the memcmp in bitmap_equal(), so fix it there, too.
      
      Fixes: 2a98dc02 ("include/linux/bitmap.h: turn bitmap_set and bitmap_clear into memset when possible")
      Fixes: 2c6deb01 ("bitmap: use memcmp optimisation in more situations")

      Pul removal of obsolete architecture ports from Arnd Bergmann:
       "This removes the entire architecture code for blackfin, cris, frv,
        m32r, metag, mn10300, score, and tile, including the associated device
        drivers.
      
        I have been working with the (former) maintainers for each one to
        ensure that my interpretation was right and the code is definitely
        unused in mainline kernels. Many had fond memories of working on the
        respective ports to start with and getting them included in upstream,
        but also saw no point in keeping the port alive without any users.
      
        In the end, it seems that while the eight architectures are extremely
        different, they all suffered the same fate: There was one company in
        charge of an SoC line, a CPU microarchitecture and a software
        ecosystem, which was more costly than licensing newer off-the-shelf
        CPU cores from a third party (typically ARM, MIPS, or RISC-V). It
        seems that all the SoC product lines are still around, but have not
        used the custom CPU architectures for several years at this point. In
        contrast, CPU instruction sets that remain popular and have actively
        maintained kernel ports tend to all be used across multiple licensees.
      
        [ See the new nds32 port merged in the previous commit for the next
          generation of "one company in charge of an SoC line, a CPU
          microarchitecture and a software ecosystem"   - Linus ]
      
        The removal came out of a discussion that is now documented at
        https://lwn.net/Articles/748074/. Unlike the original plans, I'm not
        marking any ports as deprecated but remove them all at once after I
        made sure that they are all unused. Some architectures (notably tile,
        mn10300, and blackfin) are still being shipped in products with old
        kernels, but those products will never be updated to newer kernel
        releases.
      
        After this series, we still have a few architectures without mainline
        gcc support:
      
         - unicore32 and hexagon both have very outdated gcc releases, but the
           maintainers promised to work on providing something newer. At least
           in case of hexagon, this will only be llvm, not gcc.
      
         - openrisc, risc-v and nds32 are still in the process of finishing
           their support or getting it added to mainline gcc in the first
           place. They all have patched gcc-7.3 ports that work to some
           degree, but complete upstream support won't happen before gcc-8.1.
           Csky posted their first kernel patch set last week, their situation
           will be similar
      
        [ Palmer Dabbelt points out that RISC-V support is in mainline gcc
          since gcc-7, although gcc-7.3.0 is the recommended minimum  - Linus ]"
