      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 ACPI updates from Rafael Wysocki:
       "These update the ACPICA code in the kernel to follow upstream revision
        20180313 which includes fixes related to the so-called module-level
        AML (mostly "if" type of statements outside of any methods) that
        should improve the handling of systems that load alternative SSDTs
        depending on the current configuration, for example, and event
        handling fixes related to disabling and enabling GPEs on system
        startup and on suspend/resume.
      
        Moreover, the ACPICA license boilerplate is replaced with SPDX license
        IDs which alone reduces the number of lines of ACPICA code in the
        kernel quite a bit.
      
        Also added is a new driver for the generic ACPI Time and Alarm Device
        (TAD). At the moment it only handles the most basic capabilities of
        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
        fixed, a new backlight quirk is added and some documentation is
        updated.

      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

      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 ]"
