Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull first batch of s390 updates from Martin Schwidefsky:
"The most interesting change is that Martin converted s390 to generic
hardirqs. Which means that all current architectures have been
converted and that CONFIG_GENERIC_HARDIRQS can be removed. Martin
prepared a patch for that already (see genirq branch), but the best
time to merge that is probably at the end of the merge window / begin
of -rc1.
Another patch converts s390 to software referenced bits instead of
relying on the reference bit in the storage key. Therefore s390
doesn't use storage keys anymore, except for kvm.
Besides that we have improvements, cleanups and fixes in PCI, DASD and
all over the place."
