Pull arm byte cmpxchg from Paul McKenney:
 "ARM: Provide one-byte cmpxchg emulation

  This provides emulated one-byte cmpxchg() support for ARM using the
  cmpxchg_emu_u8() function that uses a four-byte cmpxchg() to emulate
  the one-byte variant.

  Similar patches for emulation of one-byte cmpxchg() for arc, sh, and
  xtensa have not yet received maintainer acks, so they are slated for
  the v6.12 merge window"
