  "message": "locking/atomic: Fix atomic_set_release() for \u0027funny\u0027 architectures\n\nThose architectures that have a special atomic_set implementation also\nneed a special atomic_set_release(), because for the very same reason\nWRITE_ONCE() is broken for them, smp_store_release() is too.\n\nThe vast majority is architectures that have spinlock hash based atomic\nimplementation except hexagon which seems to have a hardware \u0027feature\u0027.\n\nThe spinlock based atomics should be SC, that is, none of them appear to\nplace extra barriers in atomic_cmpxchg() or any of the other SC atomic\nprimitives and therefore seem to rely on their spinlock implementation\nbeing SC (I did not fully validate all that).\n\nTherefore, the normal atomic_set() is SC and can be used at\natomic_set_release().\n\nSigned-off-by: Peter Zijlstra (Intel) \u003cpeterz@infradead.org\u003e\nAcked-by: Chris Metcalf \u003ccmetcalf@mellanox.com\u003e [for tile]\nCc: Boqun Feng \u003cboqun.feng@gmail.com\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nCc: Paul McKenney \u003cpaulmck@linux.vnet.ibm.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Will Deacon \u003cwill.deacon@arm.com\u003e\nCc: davem@davemloft.net\nCc: james.hogan@imgtec.com\nCc: jejb@parisc-linux.org\nCc: rkuo@codeaurora.org\nCc: vgupta@synopsys.com\nLink: http://lkml.kernel.org/r/20170609110506.yod47flaav3wgoj5@hirez.programming.kicks-ass.net\nSigned-off-by: Ingo Molnar \u003cmingo@kernel.org\u003e\n",
