      This reverts commit 3aa2177e.
      
      That commit triggered a new WARN when unloading the module (see at the
      end of the commit message). When a class_dev is embedded in a structure
      then that class_dev is the thing that controls the lifetime of that
      structure, for that reason device managed allocations can't be used here.
      See Documentation/kobject.txt.
      
      Revert the above patch, so the struct is allocated using kzalloc and we
      have a release function for it that frees the allocated memory, otherwise
      it is broken.
      
       ------------[ cut here ]------------
       Device 'cros_ec' does not have a release() function, it is broken and must be fixed.

      btrfs: tree-checker: Don't check max block group size as current max chunk size limit is unreliable · 10950929
      Qu Wenruo authored
      [BUG]
      A completely valid btrfs will refuse to mount, with error message like:
        BTRFS critical (device sdb2): corrupt leaf: root=2 block=239681536 slot=172 \
          bg_start=12018974720 bg_len=10888413184, invalid block group size, \
          have 10888413184 expect (0, 10737418240]
      
      This has been reported several times as the 4.19 kernel is now being
      used. The filesystem refuses to mount, but is otherwise ok and booting
      4.18 is a workaround.
      
      Btrfs check returns no error, and all kernels used on this fs is later
      than 2011, which should all have the 10G size limit commit.
      
      [CAUSE]
      For a 12 devices btrfs, we could allocate a chunk larger than 10G due to
      stripe stripe bump up.
      
      __btrfs_alloc_chunk()
      |- max_stripe_size = 1G
      |- max_chunk_size = 10G
      |- data_stripe = 11
      |- if (1G * 11 > 10G) {
             stripe_size = 976128930;
             stripe_size = round_up(976128930, SZ_16M) = 989855744
      
      However the final stripe_size (989855744) * 11 = 10888413184, which is
      still larger than 10G.
      
      [FIX]
      For the comprehensive check, we need to do the full check at chunk read
      time, and rely on bg <-> chunk mapping to do the check.
      
      We could just skip the length check for now.

      Frank Schreiner reported, that since kernel 4.18 he faces sysfs-warnings

      ("parisc: Build kernel without -ffunction-sections") we now get multiple .text
      sections in the kernel modules for which sysfs_create_group() can't create
      multiple virtual files.
      
      This patch works around the problem by re-enabling the -ffunction-sections
      compiler option for modules, while keeping it disabled for the non-module
      kernel code.

      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
           attempt
      
         - 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"
