[PATCH 4/4] (RFC) X86: add IPI tracepoints

2014-07-17 Thread Nicolas Pitre
On X86 there are already tracepoints for IRQ vectors through which IPIs are handled. However this is highly X86 specific, and the IPI signaling is not currently traced. This is an attempt at adding generic IPI tracepoints to X86. Signed-off-by: Nicolas Pitre --- arch/x86/kernel/smp.c | 16
