[PATCHv7 0/5] arm64: zboot support

[Pingfan Liu]

From: root <root at piliu.users.ipa.redhat.com>

As more complicated capsule kernel format occurs like zboot, where the
compressed kernel is stored as a payload. The straight forward
decompression can not meet the demand.
  
As the first step, on aarch64, reading in the kernel file in a probe
method and decide how to unfold the content by the method itself.

This series consists of two parts
[1/5], simplify the current aarch64 image probe
[2-5/5], return the kernel fd by the image load interface, and let the
handling of zboot image built on it. (Thanks for Dave Young, who
contributes the original idea and the code)

v6 -> v7
  Fix the included file issue in dist

v5 -> v6
  introduce kexec_info.kernel_fd and return the fd through image load
interface.
