Pull s390 updates from Martin Schwidefsky:
 "An optimization for irq-restore, the SSM instruction is quite a bit
  slower than an if-statement and a STOSM.

  The copy_file_range system all is added.

  Cleanup for PCI and CIO.

  And a couple of bug fixes"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
  s390/cio: update measurement characteristics
  s390/cio: ensure consistent measurement state
  s390/cio: fix measurement characteristics memleak
  s390/zcrypt: Fix cryptographic device id in kernel messages
  s390/pci: remove iomap sanity checks
  s390/pci: set error state for unusable functions
  s390/pci: fix bar check
  s390/pci: resize iomap
  s390/pci: improve ZPCI_* macros
  s390/pci: provide ZPCI_ADDR macro
  s390/pci: adjust IOMAP_MAX_ENTRIES
  s390/numa: move numa_init_late() from device to arch_initcall
  s390: remove all usages of PSW_ADDR_INSN
  s390: remove all usages of PSW_ADDR_AMODE
  s390: wire up copy_file_range syscall
  s390: remove superfluous memblock_alloc() return value checks
  s390/numa: allocate memory with correct alignment
  s390/irqflags: optimize irq restore
  s390/mm: use TASK_MAX_SIZE where applicable
