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] are also needed. Please use the latest one, v4 [2].
For your convinience, you can pick them up from:
   https://git.linaro.org/people/takahiro.akashi/linux-aarch64.git arm64/kdump
   https://git.linaro.org/people/takahiro.akashi/kexec-tools.git arm64/kdump

To examine vmcore (/proc/vmcore) on a crash-dump kernel, you can use
  - crash utility (v7.1.7 or later) [3]
    (As of today, the very latest tree cannot handle a core image correctly
     due to the commit 7fd8329ba502 ("taint/module: Clean up global and module
     taint flags handling")


The previous version, v27, was also:
Tested-by: Pratyush Anand <redacted> (mustang and seattle)

You have my "Tested-by" for this version as well :-). Patches works 
great after applying them over v4.10-rc2.

I used crash-utility from below where there are few patches queued for 
crash-7.1.8
