66ec24c5d7a047f5b06ee1deb1d0a2869b1791bd - Merge tag 's390-7.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Merge tag 's390-7.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linuxPull s390 updates from Vasily Gorbik: - Add a cpuidle driver with polling and enabled wait states using the existing CPU idle infrastructure and idle governor to improve latency for frequent sleep/wakeup cycles. Remove the obsolete tick delay heuristic and generic arch_needs_cpu() hook. Add the corresponding driver entry to MAINTAINERS - Add kCFI support using the generic support provided by Clang - Enable Clang CONTEXT_ANALYSIS for various architecture code and for char, PCI, CIO and virtio drivers. Add required lock annotations, exclude unsupported mm helpers and remove conditional PCI locking - Fix secure storage access exception handling and reintroduce DCACHE_WORD_ACCESS previously removed as a workaround - Fix cpum_cf perf crashes when CPUs are brought online while per-task events are active. Allocate and remove per-CPU counter data from CPU hotplug callbacks - Fix a deadlock when an s390dbf debug area is unregistered while one of its debugfs files is being written to - Fix MVIY_PERCPU() with binutils older than 2.39, where an assembler macro silently omitted an instruction needed to repair interrupted operations after CPU migration - Remove/replace cond_resched() calls which are no-ops with the supported s390 preemption models - Fix AP queue depth and maximum message length decoding according to the architecture. Current hardware is not affected, but future hardware could report values which were handled incorrectly - Reflect the configured CPU state in cpu_enabled_mask so deconfigured CPUs are not presented as available for onlining - Restore the vDSO GNU_EH_FRAME program header which was lost when the build switched to direct linker invocation, and mark it read-only - Add SCLP action qualifiers used by Spyre for card initialization, recoverable error and telemetry reporting - Move KMSAN interrupt flag helpers out of line to fix -Wstatic-in-inline build warnings - Use level-specific page table entry accessors for hugetlb entries and ptep_get() when accessing crashed kernel memory in kdump - Make forced AP bus rescans killable so that a user process blocked behind an ongoing scan can still be terminated with SIGKILL - Rework pkey ioctl error paths to remove duplicated cleanup code and avoid freeing error pointers - Allow the protected guest SWIOTLB buffer to be allocated outside the first 2GB. Also enable dynamic SWIOTLB growth and the coherent atomic pool fallback to improve I/O behavior when the initial pool is exhausted - Add program check statistics and spinlock contention tracepoints. Increase the lockdep chain capacity to keep lockdep enabled for complex code paths such as btrfs - Simplify IPL, trap and syscall code and remove the obsolete unistd_32.h generation entry* tag 's390-7.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (59 commits) s390/percpu: Fix MVIY_PERCPU() with older binutils s390/debug: Fix deadlock during unregister s390/cpum_cf: Handle CPU hotplug via prepare/dead callbacks s390: Enable CONTEXT_ANALYSIS for various directories s390/mm: Add __context_unsafe() attribute to gmap helper functions s390/mm: Add __context_unsafe() attribute to do_secure_storage_access() s390/sysinfo: Add context analysis attributes s390/irqflags: Add out-of-line definitions of arch_local_irq_*() for KMSAN s390/virtio: Enable CONTEXT_ANALYSIS s390/cio: Enable CONTEXT_ANALYSIS s390/vfio_ccw: Add __must_hold() attribute to vfio_ccw_sch_quiesce() s390/pci: Enable CONTEXT_ANALYSIS s390/pci: Rework __zpci_event_availability() to remove conditional locking s390/pci: Rework __zpci_event_error() to remove conditional locking s390/char: Enable CONTEXT_ANALYSIS s390/con3215: Add __must_hold() attribute to raw3215_make_room() s390/ap: Fix MAPML computation s390/cio: Remove cond_resched() calls s390: Remove cond_resched() calls KVM: s390: Remove cond_resched() calls ...
