Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 patches from Martin Schwidefsky:
"The biggest patch is the rework of the smp code, something I wanted to
do for some time. There are some patches for our various dump methods
and one new thing: z/VM LGR detection. LGR stands for linux-guest-
relocation and is the guest migration feature of z/VM. For debugging
purposes we keep a log of the systems where a specific guest has lived."
Fix up trivial conflict in arch/s390/kernel/smp.c due to the scheduler
cleanup having removed some code next to removed s390 code.
