Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 update from Martin Schwidefsky:
 "The most prominent change in this patch set is the software dirty bit
  patch for s390.  It removes __HAVE_ARCH_PAGE_TEST_AND_CLEAR_DIRTY and
  the page_test_and_clear_dirty primitive which makes the common memory
  management code a bit less obscure.

  Heiko fixed most of the PCI related fallout, more often than not
  missing GENERIC_HARDIRQS dependencies.  Notable is one of the 3270
  patches which adds an export to tty_io to be able to resize a tty.

  The rest is the usual bunch of cleanups and bug fixes."
