[PATCH v21 0/8] arm64: kdump support

[AKASHI Takahiro]

This patch series adds kdump support on arm64.

To load a crash-dump kernel to the systems, a series of patches to
kexec-tools [1], which have not yet been merged upstream, are needed.
Please update to the latest if you have been using an older version.

To examine vmcore (/proc/vmcore) on a crash-dump kernel, you can use
  - crash utility (coming v7.1.6 or later) [2]
    (Necessary patches have already been queued in the master.)

Changes for v21 (July 6, 2016):

  o Remove kexec patches.
  o Rebase to arm64's for-next/core (Linux-4.7-rc4 based).
  o Clarify the description about kvm in kdump.txt.
