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

Since Linus hated on cmpxchg_double(), a few patches to get rid of it, as proposed here:

https://lkml.kernel.org/r/Y2U3WdU61FvYlpUh@hirez.programming.kicks-ass.net

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.
