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
