Subject[GIT PULL] s390 patches for the 4.15 merge window #2
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.

The shortlog:

s390/vdso: add missing boot_vdso_data declaration
s390/spinlock: fix indentation
s390/mm: remove unused code
s390/nmi: remove unused code
s390: enable CPU alternatives unconditionally
s390/perf: add perf_regs support and user stack dump
s390/perf: add support for perf_regs and libdw
s390: remove unused parameter from Makefile

Hendrik Brueckner (6):
s390/cpum_sf: do not register PMU if no sampling mode is authorized
s390/perf: define common DWARF register string table
s390/perf: extend perf_regs support to include floating-point registers
s390/perf: add perf register support for floating-point registers
s390/cpum_sf: load program parameter at sampler enablement
s390/cpum_sf: correctly set the PID and TID in perf samples

Kees Cook (5):
s390: qdio: Convert timers to use timer_setup()
s390/cio: Convert timers to use timer_setup()
s390/sclp: Convert timers to use timer_setup()

Martin Schwidefsky (2):
s390/mm,kvm: improve detection of KVM guest faults
s390: remove all code using the access register mode

Michael Holzheu (1):
s390: Remove CONFIG_HARDENED_USERCOPY

Pu Hou (4):
s390/cpumf: introduce AUX buffer for dump diagnostic sample data
s390/cpumf: enable using AUX buffer
s390/perf: add callback to perf to enable using AUX buffer
s390/cpumf: remove raw event support in basic-only sampling mode

Steffen Maier (1):
zfcp: purely mechanical update using timer API, plus blank lines

Vasily Gorbik (3):
s390: correct some inline assembly constraints
s390/kbuild: get rid of a warning when compiling with KCOV
