      Pull x86 fixes from Ingo Molnar:
       "Two families of fixes:
         - Fix an FPU context related boot crash on newer x86 hardware with
           larger context sizes than what most people test.  To fix this
           without ugly kludges or extensive reverts we had to touch core task
           allocator, to allow x86 to determine the task size dynamically, at
           boot time.
           I've tested it on a number of x86 platforms, and I cross-built it
           to a handful of architectures:
                                              (warns)               (warns)
             testing     x86-64:  -git:  pass (    0),  -tip:  pass (    0)
             testing     x86-32:  -git:  pass (    0),  -tip:  pass (    0)
             testing        arm:  -git:  pass ( 1359),  -tip:  pass ( 1359)
             testing       cris:  -git:  pass ( 1031),  -tip:  pass ( 1031)
             testing       m32r:  -git:  pass ( 1135),  -tip:  pass ( 1135)
             testing       m68k:  -git:  pass ( 1471),  -tip:  pass ( 1471)
             testing       mips:  -git:  pass ( 1162),  -tip:  pass ( 1162)
             testing    mn10300:  -git:  pass ( 1058),  -tip:  pass ( 1058)
             testing     parisc:  -git:  pass ( 1846),  -tip:  pass ( 1846)
             testing      sparc:  -git:  pass ( 1185),  -tip:  pass ( 1185)
           ... so I hope the cross-arch impact 'none', as intended.

         - Fix various NMI handling related bugs unearthed by the big asm code
           rewrite and generally make the NMI code more robust and more
           maintainable while at it.  These changes are a bit late in the
           cycle, I hope they are still acceptable.

      x86/fpu, sched: Introduce CONFIG_ARCH_WANTS_DYNAMIC_TASK_STRUCT and use it on x86 · 5aaeb5c0
      Ingo Molnar authored
      Don't burden architectures without dynamic task_struct sizing
      with the overhead of dynamic sizing.
      Also optimize the x86 code a bit by caching task_struct_size.

      x86/fpu, sched: Dynamically allocate 'struct fpu' · 0c8c0f03
      Dave Hansen authored
      The FPU rewrite removed the dynamic allocations of 'struct fpu'.
      But, this potentially wastes massive amounts of memory (2k per
      task on systems that do not have AVX-512 for instance).
      Instead of having a separate slab, this patch just appends the
      space that we need to the 'task_struct' which we dynamically
      allocate already.  This saves from doing an extra slab
      allocation at fork().
      The only real downside here is that we have to stick everything
      and the end of the task_struct.  But, I think the
      BUILD_BUG_ON()s I stuck in there should keep that from being too
