Hello Linus, please pull s390 fixes and features for 5.5. Thank you, Vasily The following changes since commit da0c9ea146cbe92b832f1b0f694840ea8eb33cce: Linux 5.4-rc2 (2019-10-06 14:27:30 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git tags/s390-5.5-1 for you to fetch changes up to 6a82e23f45fe0aa821e7a935e39d0acb20c275c0: s390/cpumf: Adjust registration of s390 PMU device drivers (2019-11-20 17:16:01 +0100) ---------------------------------------------------------------- s390 updates for the 5.5 merge window - Adjust PMU device drivers registration to avoid WARN_ON and few other perf improvements. - Enhance tracing in vfio-ccw. - Few stack unwinder fixes and improvements, convert get_wchan custom stack unwinding to generic api usage. - Fixes for mm helpers issues uncovered with tests validating architecture page table helpers. - Fix noexec bit handling when hardware doesn't support it. - Fix memleak and unsigned value compared with zero bugs in crypto code. Minor code simplification. - Fix crash during kdump with kasan enabled kernel. - Switch bug and alternatives from asm to asm_inline to improve inlining decisions. - Use 'depends on cc-option' for MARCH and TUNE options in Kconfig, add z13s and z14 ZR1 to TUNE descriptions. - Minor head64.S simplification. - Fix physical to logical CPU map for SMT. - Several cleanups in qdio code. - Other minor cleanups and fixes all over the code. ---------------------------------------------------------------- Eric Farman (4): vfio-ccw: Refactor how the traces are built vfio-ccw: Trace the FSM jumptable vfio-ccw: Add a trace for asynchronous requests vfio-ccw: Rework the io_fctl trace Gerald Schaefer (4): s390/mm: make pmd/pud_bad() report large entries as bad s390/mm: simplify page table helpers for large entries s390/mm: properly clear _PAGE_NOEXEC bit when it is not supported s390/mm: add mm_pxd_folded() checks to pxd_free() Heiko Carstens (9): s390/Kconfig: make use of 'depends on cc-option' s390/Kconfig: add z13s and z14 ZR1 to TUNE descriptions s390/bug: make use of asm_inline s390/alternatives: make use of asm_inline s390/time: remove monotonic_clock() s390/time: ensure get_clock_monotonic() returns monotonic values s390: always inline current_stack_pointer() s390/pkey: fix memory leak within _copy_apqns_from_user() s390/smp: fix physical to logical CPU map for SMT Ilya Leoshkevich (3): s390/unwind: fix get_stack_pointer(NULL, NULL) s390: add error handling to perf_callchain_kernel s390/disassembler: don't hide instruction addresses Julian Wiedmann (7): s390/qdio: use QDIO_BUFNR() s390/qdio: reduce log level for EQBS partial s390/qdio: remove a forward declaration s390/qdio: add statistics helper macro s390/qdio: simplify thinint device registration s390/qdio: don't attempt IRQ avoidance on Output SBALs s390/qdio: move SSQD Sniffer mask definition Markus Elfring (1): s390/pkey: use memdup_user() to simplify code Miroslav Benes (1): s390/unwind: drop unnecessary code around calling ftrace_graph_ret_addr() Nick Desaulniers (1): s390/boot: fix section name escaping Thomas Richter (4): s390/cpum_sf: Use consistant debug print format for sampling s390/cpum_sf: Replace function name in debug statements s390/cpum_sf: Assign error value to err variable s390/cpumf: Adjust registration of s390 PMU device drivers Vasily Gorbik (7): s390: avoid double handling of "noexec" option s390/process: avoid custom stack unwinding in get_wchan Merge tag 'vfio-ccw-20191111' of https://git.kernel.org/.../kvms390/vfio-ccw into features s390/kasan: support memcpy_real with TRACE_IRQFLAGS s390/early: move control registers setup in C code s390/head64: remove unnecessary vdso_per_cpu_data setup s390/early: move access registers setup in C code YueHaibing (1): s390/crypto: Fix unsigned variable compared with zero arch/s390/Kconfig | 28 +++++++--- arch/s390/boot/startup.c | 2 +- arch/s390/crypto/sha_common.c | 7 ++- arch/s390/include/asm/alternative.h | 4 +- arch/s390/include/asm/bug.h | 4 +- arch/s390/include/asm/ctl_reg.h | 1 + arch/s390/include/asm/pgalloc.h | 16 +++++- arch/s390/include/asm/pgtable.h | 97 +++++++++++--------------------- arch/s390/include/asm/processor.h | 2 +- arch/s390/include/asm/qdio.h | 1 + arch/s390/include/asm/spinlock.h | 2 +- arch/s390/include/asm/stacktrace.h | 2 +- arch/s390/include/asm/timex.h | 17 +++--- arch/s390/kernel/dis.c | 13 +++-- arch/s390/kernel/early.c | 38 +++++++------ arch/s390/kernel/head64.S | 18 +----- arch/s390/kernel/perf_cpum_cf.c | 21 ++++--- arch/s390/kernel/perf_cpum_cf_diag.c | 10 ++-- arch/s390/kernel/perf_cpum_sf.c | 104 +++++++++++++++++------------------ arch/s390/kernel/perf_event.c | 8 ++- arch/s390/kernel/process.c | 36 ++++++------ arch/s390/kernel/smp.c | 80 ++++++++++++++++++--------- arch/s390/kernel/time.c | 9 --- arch/s390/kernel/unwind_bc.c | 14 +---- arch/s390/lib/spinlock.c | 4 +- arch/s390/mm/maccess.c | 12 ++-- drivers/s390/cio/Makefile | 4 +- drivers/s390/cio/qdio.h | 26 ++++----- drivers/s390/cio/qdio_main.c | 26 ++++----- drivers/s390/cio/qdio_setup.c | 2 - drivers/s390/cio/qdio_thinint.c | 41 +++++--------- drivers/s390/cio/vfio_ccw_cp.h | 1 + drivers/s390/cio/vfio_ccw_fsm.c | 11 ++-- drivers/s390/cio/vfio_ccw_private.h | 1 + drivers/s390/cio/vfio_ccw_trace.c | 14 +++++ drivers/s390/cio/vfio_ccw_trace.h | 76 ++++++++++++++++++++++--- drivers/s390/crypto/pkey_api.c | 26 ++------- drivers/s390/net/qeth_l3.h | 2 - drivers/s390/net/qeth_l3_sys.c | 2 +- 39 files changed, 410 insertions(+), 372 deletions(-) create mode 100644 drivers/s390/cio/vfio_ccw_trace.c
