Kairui Song 7ea0ebd4b7 arm64: kexec_file: add crash dump support 
Upstream: 3751e728cef2908c15974a5ae44627fd41ef3362
Link: 40e94ab32e

commit 3751e728cef2908c15974a5ae44627fd41ef3362

    arm64: kexec_file: add crash dump support

    Enabling crash dump (kdump) includes
    * prepare contents of ELF header of a core dump file, /proc/vmcore,
      using crash_prepare_elf64_headers(), and
    * add two device tree properties, "linux,usable-memory-range" and
      "linux,elfcorehdr", which represent respectively a memory range
      to be used by crash dump kernel and the header's location
