Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull more s390 updates from Martin Schwidefsky:
"Next to the usual bug fixes (including the TASK_SIZE fix), there is
one larger crypto item. It allows to use protected keys with the
in-kernel crypto API
The protected key support has two parts, the pkey user space API to
convert key formats and the paes crypto module that uses a protected
key instead of a standard AES key"
