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

- * struct cmbdata - channel measurement block data for user space
- * @size: size of the stored data
- * @elapsed_time: time since last sampling
- * @ssch_rsch_count: number of ssch and rsch
- * @sample_count: number of samples
- * @device_connect_time: time of device connect
- * @function_pending_time: time of function pending
- * @device_disconnect_time: time of device disconnect
- * @control_unit_queuing_time: time of control unit queuing
- * @device_active_only_time: time of device active only
- * @device_busy_time: time of device busy (ext. format)
- * @initial_command_response_time: initial command response time (ext. format)
- *
- * All values are stored as 64 bit for simplicity, especially
- * in 32 bit emulation mode. All time values are normalized to
- * nanoseconds.
- * Currently, two formats are known, which differ by the size of
- * this structure, i.e. the last two members are only set when
- * the extended channel measurement facility (first shipped in
- * z990 machines) is activated.
- * Potentially, more fields could be added, which would result in a
- * new ioctl number.
