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, v5 [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 (v7.1.8 or later, i.e. master for now) [3]

I tested this patchset on fast model and hikey.
(under various configurations, in particular 4KB-page/39,48-bits, 64KB-page/42
-bits with hibernate)

The previous versions were also:
Tested-by: Pratyush Anand <redacted> (v29, mustang and seattle)
Tested-by: James Morse <james.morse@arm.com> (v27, Juno)

I tested this patch set on a QDT2400 device with 4k 4-level setup. This patchset worked after applying [1].

Thank you for your test and report.
While adding [1] is yet to be discussed, I will post v33 as soon as
possible after v4.10-rc1.

Thanks,
-Takahiro AKASHI

[1] [PATCH] efi/libstub/arm*: Set default address and size cells values for an empty dtb

Without the above patch the start address of the crash kernel is recorded incorrectly and the 
memblock_cap_memory_range clears out the incorrect range. 
 
Thanks,
Sameer
