If anyone has any objections, please let me know. ------------------ From: Vasily Gorbik commit 15deb080a6087b73089139569558965750e69d67 upstream. When loadparm is set in reipl parm block, the kernel should also set DIAG308_FLAGS_LP_VALID flag. This fixes loadparm ignoring during z/VM fcp -> ccw reipl and kvm direct boot -> ccw reipl.
