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

Pull s390 updates from Martin Schwidefsky:

 - A couple of patches for the zcrypt driver:
     + Add two masks to determine which AP cards and queues are host
       devices, this will be useful for KVM AP device passthrough
     + Add-on patch to improve the parsing of the new apmask and aqmask
     + Some code beautification

 - Second try to reenable the GCC plugins, the first patch set had a
   patch to do this but the merge somehow missed this

 - Remove the s390 specific GCC version check and use the generic one

 - Three patches for kdump, two bug fixes and one cleanup

 - Three patches for the PCI layer, one bug fix and two cleanups

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
  s390: remove gcc version check (4.3 or newer)
  s390/zcrypt: hex string mask improvements for apmask and aqmask.
  s390/zcrypt: AP bus support for alternate driver(s)
  s390/zcrypt: code beautify
  s390/zcrypt: switch return type to bool for ap_instructions_available()
  s390/kdump: Remove kzalloc_panic
  s390/kdump: Fix memleak in nt_vmcoreinfo
  s390/kdump: Make elfcorehdr size calculation ABI compliant
  s390/pci: remove fmb address from debug output
  s390/pci: remove stale rc
  s390/pci: fix out of bounds access during irq setup
  s390/zcrypt: fix ap_instructions_available() returncodes
  s390: reenable gcc plugins for real
