Linus, The following changes since commit e2e83a73d7ce66f62c7830a85619542ef59c90e4: docs: kvm: fix WARNINGs from api.rst (2022-01-20 12:13:35 -0500) are available in the Git repository at: https://git.kernel.org/pub/scm/virt/kvm/kvm.git tags/for-linus for you to fetch changes up to 17179d0068b20413de2355f84c75a93740257e20: Merge tag 'kvmarm-fixes-5.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD (2022-01-28 07:45:15 -0500) ---------------------------------------------------------------- Two larger x86 series: * Redo incorrect fix for SEV/SMAP erratum * Windows 11 Hyper-V workaround Other x86 changes: * Various x86 cleanups * Re-enable access_tracking_perf_test * Fix for #GP handling on SVM * Fix for CPUID leaf 0Dh in KVM_GET_SUPPORTED_CPUID * Fix for ICEBP in interrupt shadow * Avoid false-positive RCU splat * Enable Enlightened MSR-Bitmap support for real ARM: * Correctly update the shadow register on exception injection when running in nVHE mode * Correctly use the mm_ops indirection when performing cache invalidation from the page-table walker * Restrict the vgic-v3 workaround for SEIS to the two known broken implementations Generic code changes: * Dead code cleanup There will be another pull request for ARM fixes next week, but those patches need a bit more soak time.
