  "message": "x86, mm, perf: Allow recursive faults from interrupts\n\nWaiman managed to trigger a PMI while in a emulate_vsyscall() fault,\nthe PMI in turn managed to trigger a fault while obtaining a stack\ntrace. This triggered the sig_on_uaccess_error recursive fault logic\nand killed the process dead.\n\nFix this by explicitly excluding interrupts from the recursive fault\nlogic.\n\nReported-and-Tested-by: Waiman Long \u003cwaiman.long@hp.com\u003e\nFixes: e00b12e64be9 (\"perf/x86: Further optimize copy_from_user_nmi()\")\nCc: Aswin Chandramouleeswaran \u003caswin@hp.com\u003e\nCc: Scott J Norton \u003cscott.norton@hp.com\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nCc: Andy Lutomirski \u003cluto@amacapital.net\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@ghostprotocols.net\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nLink: http://lkml.kernel.org/r/20140110200603.GJ7572@laptop.programming.kicks-ass.net\nSigned-off-by: Ingo Molnar \u003cmingo@kernel.org\u003e\n",
