Philipp Rudo a874333de0 s390/kexec_file: fix diag308 subcode when loading crash kernel ... commit 613775d62e upstream. diag308 subcode 0 performes a clear reset which inlcudes the reset of all registers in the system. While this is the preferred behavior when loading a normal kernel via kexec it prevents the crash kernel to store the register values in the dump. To prevent this use subcode 1 when loading a crash kernel instead.
