Thanks, Heiko The following changes since commit 94d3477897481b92874654455e263e0b1728acb5: s390/head: get rid of 31 bit leftovers (2022-05-18 13:31:07 +0200) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git tags/s390-5.19-2 for you to fetch changes up to e0ffcf3fe18e0310221461c08969edec2cc7628c: s390/stack: add union to reflect kvm stack slot usages (2022-06-01 12:03:17 +0200) ---------------------------------------------------------------- more s390 updates for 5.19 merge window - Add Eric Farman as maintainer for s390 virtio drivers. - Improve machine check handling, and avoid incorrectly injecting a machine check into a kvm guest. - Add cond_resched() call to gmap page table walker in order to avoid possible huge latencies. Also use non-quiesing sske instruction to speed up storage key handling. - Add __GFP_NORETRY to KEXEC_CONTROL_MEMORY_GFP so s390 behaves similar like common code. - Get sie control block address from correct stack slot in perf event code. This fixes potential random memory accesses. - Change uaccess code so that the exception handler sets the result of get_user() and __get_kernel_nofault() to zero in case of a fault. Until now this was done via input parameters for inline assemblies. Doing it via fault handling is what most or even all other architectures are doing. - Couple of other small cleanups and fixes. ---------------------------------------------------------------- Alexander Gordeev (1): s390/mcck: isolate SIE instruction when setting CIF_MCCK_GUEST flag Christian Borntraeger (2): s390/gmap: voluntarily schedule during key setting s390/mm: use non-quiescing sske for KVM switch to keyed guest Eric Farman (1): MAINTAINERS: Update s390 virtio-ccw Heiko Carstens (9): s390: simplify early program check handler s390: generate register offsets into pt_regs automatically s390/kexec: add __GFP_NORETRY to KEXEC_CONTROL_MEMORY_GFP s390/uaccess: use symbolic names for inline assembler operands s390/uaccess: use exception handler to zero result on get_user() failure s390/uaccess: use __noreturn instead of __attribute__((noreturn)) s390/uaccess: whitespace cleanup s390/stack: merge empty stack frame slots s390/stack: add union to reflect kvm stack slot usages Jann Horn (1): s390/crypto: fix scatterwalk_unmap() callers in AES-GCM Juerg Haefliger (2): s390/Kconfig: fix indentation s390/Kconfig.debug: fix indentation Nico Boehr (1): s390/perf: obtain sie_block from the right address MAINTAINERS | 1 + arch/s390/Kconfig | 8 +- arch/s390/Kconfig.debug | 12 +- arch/s390/crypto/aes_s390.c | 4 +- arch/s390/include/asm/asm-extable.h | 91 +++++++++----- arch/s390/include/asm/kexec.h | 2 +- arch/s390/include/asm/processor.h | 6 - arch/s390/include/asm/stacktrace.h | 11 +- arch/s390/include/asm/uaccess.h | 217 +++++++++++++++++--------------- arch/s390/kernel/Makefile | 2 +- arch/s390/kernel/asm-offsets.c | 26 +++- arch/s390/kernel/early.c | 5 +- arch/s390/kernel/{base.S => earlypgm.S} | 33 +---- arch/s390/kernel/entry.S | 23 +--- arch/s390/kernel/entry.h | 2 + arch/s390/kernel/perf_event.c | 2 +- arch/s390/mm/extable.c | 39 +++++- arch/s390/mm/gmap.c | 14 +++ arch/s390/mm/pgtable.c | 2 +- 19 files changed, 289 insertions(+), 211 deletions(-) rename arch/s390/kernel/{base.S => earlypgm.S} (52%)
