[Martin Schwidefsky]

Hi Linus,

please pull from the 'for-linus' branch of

	git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git for-linus

to receive the following updates:

The second part of the s390 patches for the 4.15 merge window:

 - 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.
