[PATCH 0/2] s390/ipl: Fix missing re-IPL parm blocks handling in dump paths

HMC FTP boot and QEMU direct kernel boot do not provide an IPL parameter
block. This can lead to NULL pointer dereferences during kdump and
stand-alone dump processing.

Fix the kdump and stand-alone dump paths separately. kdump continues
without a re-IPL parameter block, while the stand-alone dumper completes
the dump and halts.

  s390/ipl: Fix NULL deref in dump_reipl without re-IPL parm block
