Linus, The following changes since commit 136057256686de39cc3a07c2e39ef6bc43003ff6: Linux 5.16-rc2 (2021-11-21 13:47:39 -0800) 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 7cfc5c653b07782e7059527df8dc1e3143a7591e: KVM: fix avic_set_running for preemptable kernels (2021-11-30 07:40:48 -0500) ---------------------------------------------------------------- ARM64: * Fix constant sign extension affecting TCR_EL2 and preventing running on ARMv8.7 models due to spurious bits being set * Fix use of helpers using PSTATE early on exit by always sampling it as soon as the exit takes place * Move pkvm's 32bit handling into a common helper RISC-V: * Fix incorrect KVM_MAX_VCPUS value * Unmap stage2 mapping when deleting/moving a memslot x86: * Fix and downgrade BUG_ON due to uninitialized cache * Many APICv and MOVE_ENC_CONTEXT_FROM fixes * Correctly emulate TLB flushes around nested vmentry/vmexit and when the nested hypervisor uses VPID * Prevent modifications to CPUID after the VM has run * Other smaller bugfixes Generic: * Memslot handling bugfixes ---------------------------------------------------------------- This is the large bugfix pull request that I mentioned just before rc2, with the APICv and MOVE_ENC_CONTEXT_FROM/COPY_ENC_CONTEXT_FROM bug shakedown. It missed rc3 due to Thanksgiving (half of the patches are mine and I wanted to get reviews on them for obvious reasons).
