Linus, The following changes since commit 18c841e1f4112d3fb742aca3429e84117fcb1e1c: KVM: x86: Retry page fault if MMU reload is pending and root has no sp (2021-12-19 19:38:58 +0100) 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 fdba608f15e2427419997b0898750a49a735afcb: KVM: VMX: Wake vCPU when delivering posted IRQ even if vCPU == this vCPU (2021-12-21 12:39:03 -0500) ---------------------------------------------------------------- * Fix for compilation of selftests on non-x86 architectures * Fix for kvm_run->if_flag on SEV-ES * Fix for page table use-after-free if yielding during exit_mm() * Improve behavior when userspace starts a nested guest with invalid state * Fix missed wakeup with assigned devices but no VT-d posted interrupts * Do not tell userspace to save/restore an unsupported PMU MSR ---------------------------------------------------------------- So, 5.16 really was a huge bug shakedown for KVM. Apart from the locking changes in -rc4, almost everything that went in after -rc2 was Cc'ed stable, including this pull request (which I guess is not a bad thing for rc7). You can't quite see it, but things do seem to have calmed down; these patches as well as those in rc6 had actually been submitted a week or so ago; one was a relatively old 5.17 change that turned out to fix a bug. Since I'm taking some time off until right before the merge window, I don't expect any more changes in 5.16. Thanks for putting up with this weird KVM release cycle.
