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 * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (30 commits) s390: remove unused parameter from Makefile zfcp: purely mechanical update using timer API, plus blank lines s390/scsi: Convert timers to use timer_setup() s390/cpum_sf: correctly set the PID and TID in perf samples s390/cpum_sf: load program parameter at sampler enablement s390/perf: add perf register support for floating-point registers s390/perf: extend perf_regs support to include floating-point registers s390/perf: define common DWARF register string table s390/perf: add support for perf_regs and libdw s390/perf: add perf_regs support and user stack dump s390/cpum_sf: do not register PMU if no sampling mode is authorized s390/cpumf: remove raw event support in basic-only sampling mode s390/perf: add callback to perf to enable using AUX buffer s390/cpumf: enable using AUX buffer s390/cpumf: introduce AUX buffer for dump diagnostic sample data s390/disassembler: increase show_code buffer size s390: Remove CONFIG_HARDENED_USERCOPY s390: enable CPU alternatives unconditionally s390/nmi: remove unused code s390/mm: remove unused code ...
