* Avoid dropping the page refcount twice when freeing an unlinked page-table subtree. * Don't source the VFIO Kconfig twice * Fix protected-mode locking order between kvm and vcpus RISC-V: * Fix steal-time related sparse warnings x86: * Cleanup gtod_is_based_on_tsc() to return "bool" instead of an "int" * Make a KVM_REQ_NMI request while handling KVM_SET_VCPU_EVENTS if and only if the incoming events->nmi.pending is non-zero. If the target vCPU is in the UNITIALIZED state, the spurious request will result in KVM exiting to userspace, which in turn causes QEMU to constantly acquire and release QEMU's global mutex, to the point where the BSP is unable to make forward progress. * Fix a type (u8 versus u64) goof that results in pmu->fixed_ctr_ctrl being incorrectly truncated, and ultimately causes KVM to think a fixed counter has already been disabled (KVM thinks the old value is '0'). * Fix a stack leak in KVM_GET_MSRS where a failed MSR read from userspace that is ultimately ignored due to ignore_msrs=true doesn't zero the output as intended. Selftests cleanups and fixes: * Remove redundant newlines from error messages. * Delete an unused variable in the AMX test (which causes build failures when compiling with -Werror). * Fail instead of skipping tests if open(), e.g. of /dev/kvm, fails with an error code other than ENOENT (a Hyper-V selftest bug resulted in an EMFILE, and the test eventually got skipped). * Fix TSC related bugs in several Hyper-V selftests. * Fix a bug in the dirty ring logging test where a sem_post() could be left pending across multiple runs, resulting in incorrect synchronization between the main thread and the vCPU worker thread. * Relax the dirty log split test's assertions on 4KiB mappings to fix false positives due to the number of mappings for memslot 0 (used for code and data that is NOT being dirty logged) changing, e.g. due to NUMA balancing. -----BEGIN PGP SIGNATURE----- iQFIBAABCAAyFiEE8TM4V0tmI4mGbHaCv/vSX3jHroMFAmXPlokUHHBib256aW5p QHJlZGhhdC5jb20ACgkQv/vSX3jHroPs3AgApdYANmMEy2YaUZLYsQOEP388vLEf +CS9kChY6xWuYzdFPTpM4BqNVn46zPh+HDEHTCJy1eOLpeOg6HbaNGuF/1G98+HF COm7C2bWOrGAL/UMzPzciyEMQFE7c/h28Yuq/4XpyDNrFbnChYxPh9W4xexqoLhV QtGYU03guLCUsI5veY0rOrSJ5xEu9f8c63JH5JPahtbMB0uNoi0Kz7i86sbkkUg7 OcTra+j/FyGVAWwEJ8Q2hcGlKn4DMeyQ/riUvPrfSarTqC6ZswKltg9EMSxNnojE LojijqRFjKklkXonnalVeDzJbG0OWHks8VO6JmCJdt0zwBRei0iLWi2LEg== =8/la -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull KVM fixes from Paolo Bonzini: "ARM: - Avoid dropping the page refcount twice when freeing an unlinked page-table subtree. - Don't source the VFIO Kconfig twice - Fix protected-mode locking order between kvm and vcpus RISC-V: - Fix steal-time related sparse warnings x86: - Cleanup gtod_is_based_on_tsc() to return "bool" instead of an "int" - Make a KVM_REQ_NMI request while handling KVM_SET_VCPU_EVENTS if and only if the incoming events->nmi.pending is non-zero.
