  "message": "irq: only update affinity if -\u003eset_affinity() is sucessfull\n\nirq_set_affinity() and move_masked_irq() try to assign affinity\nbefore calling chip set_affinity(). Some archs are assigning it\nin -\u003eset_affinity() again.\n\nWe do something like:\n\n cpumask_cpy(desc-\u003eaffinity, mask);\n desc-\u003echip-\u003eset_affinity(mask);\n\nBut in the failure path, affinity should not be touched - otherwise\nwe\u0027ll end up with a different affinity mask despite the failure to\nmigrate the IRQ.\n\nSo try to update the afffinity only if set_affinity returns with 0.\nAlso call irq_set_thread_affinity accordingly.\n\nv2: update after \"irq, x86: Remove IRQ_DISABLED check in process context IRQ move\"\nv3: according to Ingo, change set_affinity() in irq_chip should return int.\nv4: update comments by removing moving irq_desc code.\n\n[ Impact: fix /proc/irq/*/smp_affinity setting corner case bug ]\n\nSigned-off-by: Yinghai Lu \u003cyinghai@kernel.org\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: Suresh Siddha \u003csuresh.b.siddha@intel.com\u003e\nCc: \"Eric W.
