Phil Carmody 9414e99672 oprofile: protect from not being in an IRQ context ... http://lkml.org/lkml/2010/4/27/285 Protect against dereferencing regs when it's NULL, and force a magic number into pc to prevent too deep processing. This approach permits the dropped samples to be tallied as invalid Instruction Pointer events. e.g. output from about 15mins at 10kHz sample rate: Nr. samples received: 2565380 Nr. samples lost invalid pc: 4 Signed-off-by: Phil Carmody <ext-phil.2.carmody@nokia.com> Signed-off-by: Robert Richter <robert.richter@amd.com>		15 years ago
