  "message": "Add irq protection in the percpu-counters cpu-hotplug-callback path\n\nSome of the per-cpu counters and thus their locks are accessed from IRQ\ncontexts.  This can cause a deadlock if it interrupts a cpu-offline thread\nwhich is transferring a dead-cpu\u0027s counts to the global counter.\n\nAdd appropriate IRQ protection in the cpu-hotplug callback path.\n\nSigned-off-by: Gautham R Shenoy \u003cego@in.ibm.com\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
