[Crash-utility] [PATCH v4 0/3] arm64: more improvement of bt -f

[AKASHI Takahiro]

Changes in v4:
* use arm64_on_irq_stack() to check whether or not we are on IRQ stack.
  mistakendly used 'flags & IRQ_STACKS'.
* fix a bug at critical timing around switching stacks in arm64_unwind_frame().
  We need to take are of a possibility that we get back to process stack,
  but fp still points to IRQ stack.
* add patch[2/3]
  This should be applied even withtout patch[1/3]
* add patch[3/3]
  applying this patch would be a discussion.
