[PATCH v2 0/3] lkdtm: fix irq handler entry for arm64

[AKASHI Takahiro]

Lkdtm is a handy way for testing kdump in case of panic in interrupt
context:
   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 the rest and allows for probing any
exception entries, including irq handler, on arm64.
Patch#2 provides a generalized approach for this issue on lkdtm side.
Patch#3 is an arm64-specific fix.

As a hint for further improvement, another hook doesn't work neither:
* hrtimer_start() was converted to an inline function in v4.2
but I don't know how we should deal with them.
(In my v1, I also mentioned handle_IRQ_event, but it was a wrong claim.)

Changes in v2(Feb 27, 2018):
* provide a generalized approach instead of adding "if (CONFIG_ARM64)"
  stuff
