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
