Hi Linus,

please pull from the 'for-linus' branch of

git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git for-linus

to receive the following updates:

Revert the re-IPL semantics back to the v4.7 state. It turned out that the memory layout may change due to memory hotplug if load-normal is used.

Heiko Carstens (1):
s390/ipl: revert Load Normal semantics for LPAR CCW-type re-IPL
