Linus Torvalds 2e57d1d606 sparc32,parisc,csky: Provide one-byte and two-byte cmpxchg() support

This series provides native one-byte and two-byte cmpxchg() support
 for sparc32 and parisc, courtesy of Al Viro.  This support is provided
 by the same hashed-array-of-locks technique used for the other atomic
 operations provided for these two platforms.
 
 This series also provides emulated one-byte cmpxchg() support for csky
 using a new 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 v6.11 merge window.
