[RFC][PATCH 00/12] Introduce cmpxchg128() -- aka. the demise of cmpxchg_double()

[Peter Zijlstra]

  https://lkml.kernel.org/r/Y2U3WdU61FvYlpUh@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

based on tip/master because Linus' tree is moving a wee bit fast at the moment.

0day robot is all green for building, very limited testing on arm64/s390
for obvious raisins -- I tried to get the asm right, but please, double
check.
