  This patch series is a follow-up to [1] based on discussions at [2]
about additional work needed to get it working on powerpc.

The first patch in the series makes struct crash_mem available with or
without CONFIG_CRASH_DUMP enabled. The next patch moves kdump specific
code for kexec_file_load syscall under CONFIG_CRASH_DUMP and the last
patch splits other kdump specific code under CONFIG_CRASH_DUMP and
removes dependency with CONFIG_CRASH_DUMP for CONFIG_KEXEC_CORE.
