Nicolas Pitre f6d9804d14 tracepoint: add generic tracepoint definitions for IPI tracing ... The Inter Processor Interrupt is used to make another processor do a specific action such as rescheduling tasks, signal a timer event or execute something in another CPU's context. IRQs are already traceable but IPIs were not. Tracing them is useful for monitoring IPI latency, or to verify when they are the source of CPU wake-ups with power management implications. Three trace hooks are defined: ipi_raise, ipi_entry and ipi_exit. To make them portable, a string is used to identify them and correlate related events. Additionally, ipi_raise records a bitmask representing targeted CPUs.
