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
