Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux
Pull second round of s390 updates from Martin Schwidefsky:
- rework of the vdso code to avoid the use of the access register mode
- use perf AUX buffers for the transport of diagnostic sample data
- add perf_regs and user stack dump support
- enable perf call graphs for user space programs
- add perf register support for floating-point registers
- all remaining s390 related timer_setup conversions
- bug fixes and cleanups
