Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull s390 updates from Martin Schwidefsky:
"The major change in this merge is the removal of the support for
31-bit kernels. Naturally 31-bit user space will continue to work via
the compat layer.
And then some cleanup, some improvements and bug fixes"
