Philipp Rudo bc8f8833e9 s390/kexec_file: fix diag308 subcode when loading crash kernel ... commit 613775d62ec60202f98d2c5f520e6e9ba6dd4ac4 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.
