      Pull ARM SoC fixes from Olof Johansson:
       "Volume is a little higher than usual due to a set of gpio fixes for
        Davinci platforms that's been around a while, still seemed appropriate
        to not hold off until next merge window.
        Besides that it's the usual mix of minor fixes, mostly corrections of
        small stuff in device trees.
        Major stability-related one is the removal of a regulator from DT on
        Rock960, since DVFS caused undervoltage. I expect it'll be restored
        once they figure out the underlying issue"

      Pull STIBP fallout fixes from Thomas Gleixner:
       "The performance destruction department finally got it's act together
        and came up with a cure for the STIPB regression:
         - Provide a command line option to control the spectre v2 user space
           mitigations. Default is either seccomp or prctl (if seccomp is
           disabled in Kconfig). prctl allows mitigation opt-in, seccomp
           enables the migitation for sandboxed processes.
         - Rework the code to handle the conditional STIBP/IBPB control and
           remove the now unused ptrace_may_access_sched() optimization
         - Disable STIBP automatically when SMT is disabled
         - Optimize the switch_to() logic to avoid MSR writes and invocations
           of __switch_to_xtra().
         - Make the asynchronous speculation TIF updates synchronous to
           prevent stale mitigation state.
        As a general cleanup this also makes retpoline directly depend on
        compiler support and removes the 'minimal retpoline' option which just
        pretended to provide some form of security while providing none"

      PCI: Fix incorrect value returned from pcie_get_speed_cap() · f1f90e25
      Mikulas Patocka authored
      The macros PCI_EXP_LNKCAP_SLS_*GB are values, not bit masks.  We must mask
      the register and compare it against them.
      This fixes errors like this:
        amdgpu: [powerplay] failed to send message 261 ret is 0
      when a PCIe-v3 card is plugged into a PCIe-v1 slot, because the slot is
      being incorrectly reported as PCIe-v3 capable.
      6cf57be0, which appeared in v4.17, added pcie_get_speed_cap() with the
      incorrect test of PCI_EXP_LNKCAP_SLS as a bitmask.  5d9a6330, which
      appeared in v4.19, changed amdgpu to use pcie_get_speed_cap(), so the
      amdgpu bug reports below are regressions in v4.19.
      Fixes: 6cf57be0 ("PCI: Add pcie_get_speed_cap() to find max supported link speed")
      Fixes: 5d9a6330 ("drm/amdgpu: use pcie functions for link width and speed")

      Pull fscache and cachefiles fixes from David Howells:
       "Misc fixes:
         - Fix an assertion failure at fs/cachefiles/xattr.c:138 caused by a
           race between a cache object lookup failing and someone attempting
           to reenable that object, thereby triggering an update of the
           object's attributes.
         - Fix an assertion failure at fs/fscache/operation.c:449 caused by a
           split atomic subtract and atomic read that allows a race to happen.
         - Fix a leak of backing pages when simultaneously reading the same
           page from the same object from two or more threads.
         - Fix a hang due to a race between a cache object being discarded and
           the corresponding cookie being reenabled.
        There are also some minor cleanups:
         - Cast an enum value to a different enum type to prevent clang from
           generating a warning. This shouldn't cause any sort of change in
           the emitted code.
         - Use ktime_get_real_seconds() instead of get_seconds(). This is just
           used to uniquify a filename for an object to be placed in the
           graveyard. Objects placed there are deleted by cachfilesd in
           userspace immediately thereafter.
         - Remove an initialised, but otherwise unused variable. This should
           have been entirely optimised away anyway"
