Thomas Gleixner a5497bab5f entry: Provide generic interrupt entry/exit code ... Like the syscall entry/exit code interrupt/exception entry after the real low level ASM bits should not be different accross architectures. Provide a generic version based on the x86 code. irqentry_enter() is called after the low level entry code and irqentry_exit() must be invoked right before returning to the low level code which just contains the actual return logic. The code before irqentry_enter() and irqentry_exit() must not be instrumented. Code after irqentry_enter() and before irqentry_exit() can be instrumented. irqentry_enter() invokes irqentry_enter_from_user_mode() if the interrupt/exception came from user mode. If if entered from kernel mode it handles the kernel mode variant of establishing state for lockdep, RCU and tracing depending on the kernel context it interrupted (idle, non-idle).
