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.
