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

Pull second s390 update from Martin Schwidefsky:
 "The big thing in this pull request is the UAPI patch from David, and
  worth mentioning is the page table dumper.  The rest are small
  improvements and bug fixes."

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
  s390/entry: fix svc number for TIF_SYSCALL system call restart
  s390/mm,vmem: fix vmem_add_mem()/vmem_remove_range()
  s390/vmalloc: have separate modules area
  s390/zcrypt: remove duplicated include from zcrypt_pcixcc.c
  s390/css_chars: remove superfluous ifdef
  s390/chsc: make headers usable
  s390/mm: let kernel text section always begin at 1MB
  s390/mm: fix mapping of read-only kernel text section
  s390/mm: add page table dumper
  s390: add support to start the kernel in 64 bit mode.
  s390/mm,pageattr: remove superfluous EXPORT_SYMBOLs
  s390/mm,pageattr: add more page table walk sanity checks
  s390/mm: fix pmd_huge() usage for kernel mapping
  s390/dcssblk: cleanup device attribute usage
  s390/mm: use pfmf instruction to initialize storage keys
  s390/facilities: cleanup PFMF and HPAGE machine facility detection
  UAPI: (Scripted) Disintegrate arch/s390/include/asm

---help---
Say Y here if you want to show the kernel pagetable layout in a
debugfs file. This information is only useful for kernel developers
who are working in architecture specific areas of the kernel.
It is probably not a good idea to enable this feature in a production
kernel.
If in doubt, say "N"
