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

Pull s390 updates from Martin Schwidefsky:
 "This is the bulk of the s390 patches for the 3.11 merge window.

  Notable enhancements are: the block timeout patches for dasd from
  Hannes, and more work on the PCI support front.  In addition some
  cleanup and the usual bug fixing."
