  "message": "arch: Prepare for smp_mb__{before,after}_atomic()\n\nSince the smp_mb__{before,after}*() ops are fundamentally dependent on\nhow an arch can implement atomics it doesn\u0027t make sense to have 3\nvariants of them. They must all be the same.\n\nFurthermore, the 3 variants suggest they\u0027re only valid for those 3\natomic ops, while we have many more where they could be applied.\n\nSo move away from\nsmp_mb__{before,after}_{atomic,clear}_{dec,inc,bit}() and reduce the\ninterface to just the two: smp_mb__{before,after}_atomic().\n\nThis patch prepares the way by introducing default implementations in\nasm-generic/barrier.h that default to a full barrier and providing\n__deprecated inlines for the previous 6 barriers if they\u0027re not\nprovided by the arch.\n\nThis should allow for a mostly painless transition (lots of deprecated\nwarns in the interim).\n\nSigned-off-by: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nAcked-by: Paul E.
