[PATCH 0/2] lkdtm: fix irq handler entry for arm64

Lkdtm is a handy way for testing kdump in case of panic in interrupt
echo PANIC > /sys/kernel/debug/provoke-crash/INT_HARDWARE_ENTRY
But this just doesn't work on arm64 since "do_IRQ" function doesn't
exist on arm64. This patch series addresses this problem.
Patch#1 is a preliminary fix for patch#2 and allows for probing any
exception entries, including irq handler.
For further improvements, some of other hooks doesn't work:
* handle_IRQ_event() was removed in v2.6.39
* hrtimer_start() was converted to an inline function in v4.2
but I don't know how we should deal with them.
