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

Pull second set of s390 patches from Martin Schwidefsky:
 "The handling of the PCI hotplug notifications has been improved, the
  zfcp dumper can now detect the HSA size dynamically and the default
  install kernel has been changed to the compressed bzImage.  And two
  bug-fixes for scm and 3720"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
  s390/pci: implement hotplug notifications
  s390/scm_block: do not hide eadm subchannel dependency
  s390/sclp: Consolidate early sclp init calls to sclp_early_detect()
  s390/sclp: Move early code from sclp_cmd.c to sclp_early.c
  s390/sclp: Determine HSA size dynamically for zfcpdump
  s390/sclp: Move declarations for sclp_sdias into separate header file
  s390/pci: implement pcibios_remove_bus
  s390/pci: improve handling of bus resources
  s390/3270: fix missing device_destroy() call
  s390/boot: Install bzImage as default kernel image
