       "A collection of small, mostly device-specific fixes.
      
        The significant one is the regression fix for USB-audio implicit
        feedback devices due to the incorrect frame size calculation, which
        landed in 5.8 and stable trees.
      
        In addition, a few usual HD-audio and USB-audio quirks, Intel HDMI
        fixes, ASoC fsl and rt5682 fixes, as well as the fix in
        compress-offload partial drain operation"

      Raise gcc version requirement to 4.9 · 6ec4476a
      Linus Torvalds authored
      I realize that we fairly recently raised it to 4.8, but the fact is, 4.9
      is a much better minimum version to target.
      
      We have a number of workarounds for actual bugs in pre-4.9 gcc versions
      (including things like internal compiler errors on ARM), but we also
      have some syntactic workarounds for lacking features.
      
      In particular, raising the minimum to 4.9 means that we can now just
      assume _Generic() exists, which is likely the much better replacement
      for a lot of very convoluted built-time magic with conditionals on
      sizeof and/or __builtin_choose_expr() with same_type() etc.
      
      Using _Generic also means that you will need to have a very recent
      version of 'sparse', but thats easy to build yourself, and much less of
      a hassle than some old gcc version can be.
      
      The latest (in a long string) of reasons for minimum compiler version
      upgrades was commit 5435f73d ("efi/x86: Fix build with gcc 4").
      
      Ard points out that RHEL 7 uses gcc-4.8, but the people who stay back on
      old RHEL versions persumably also don't build their own kernels anyway.
      And maybe they should cross-built or just have a little side affair with
      a newer compiler?

      x86/ldt: use "pr_info_once()" instead of open-coding it badly · bb5a93aa
      Linus Torvalds authored
      Using a mutex for "print this warning only once" is so overdesigned as
      to be actively offensive to my sensitive stomach.
      
      Just use "pr_info_once()" that already does this, although in a
      (harmlessly) racy manner that can in theory cause the message to be
      printed twice if more than one CPU races on that "is this the first
      time" test.
      
      [ If somebody really cares about that harmless data race (which sounds
        very unlikely indeed), that person can trivially fix printk_once() by
        using a simple atomic access, preferably with an optimistic non-atomic
        test first before even bothering to treat the pointless "make sure it
        is _really_ just once" case.
      
        A mutex is most definitely never the right primitive to use for
        something like this. ]
      
      Yes, this is a small and meaningless detail in a code path that hardly
      matters.  But let's keep some code quality standards here, and not
      accept outrageously bad code.

       "A series of fixes for x86:
      
         - Reset MXCSR in kernel_fpu_begin() to prevent using a stale user

         - Prevent writing MSR_TEST_CTRL on CPUs which are not explicitly
           whitelisted for split lock detection. Some CPUs which do not
           support it crash even when the MSR is written to 0 which is the
           default value.
      
         - Fix the XEN PV fallout of the entry code rework
      
         - Fix the 32bit fallout of the entry code rework
      
         - Add more selftests to ensure that these entry problems don't come
           back.

           PV does not implement ESPFIX64"
