Please pull a random smattering of fixes for 6.16. Note, the SEV-ES intra-host migration commits received your "Queued, thanks", but they never showed up in kvm.git. Oh, and there's one more fix that is probably a candidate for 6.16, but I'm waiting for a response from the submitter, as I think we can go with a more targeted fix: https://lore.kernel.org/all/aFwLpyDYOsHUtCn-@xxxxxxxxxx The following changes since commit 28224ef02b56fceee2c161fe2a49a0bb197e44f5: KVM: TDX: Report supported optional TDVMCALLs in TDX capabilities (2025-06-20 14:20:20 -0400) are available in the Git repository at: https://github.com/kvm-x86/linux.git tags/kvm-x86-fixes-6.16-rcN for you to fetch changes up to fa787ac07b3ceb56dd88a62d1866038498e96230: KVM: x86/hyper-v: Skip non-canonical addresses during PV TLB flush (2025-06-25 09:15:24 -0700) ---------------------------------------------------------------- KVM x86 fixes for 6.16-rcN - Reject SEV{-ES} intra-host migration if one or more vCPUs are actively being created so as not to create a non-SEV{-ES} vCPU in an SEV{-ES} VM. - Use a pre-allocated, per-vCPU buffer for handling de-sparsified vCPU masks when emulating Hyper-V hypercalls to fix a "stack frame too large" issue. - Allow out-of-range/invalid Xen event channel ports when configuring IRQ routing to avoid dictating a specific ioctl() ordering to userspace. - Conditionally reschedule when setting memory attributes to avoid soft lockups when userspace converts huge swaths of memory to/from private. - Add back MWAIT as a required feature for the MONITOR/MWAIT selftest. - Add a missing field in struct sev_data_snp_launch_start that resulted in the guest-visible workarounds field being filled at the wrong offset. - Skip non-canonical address when processing Hyper-V PV TLB flushes to avoid VM-Fail on INVVPID. ---------------------------------------------------------------- Binbin Wu (1): Documentation: KVM: Fix unexpected unindent warnings Chenyi Qiang (1): KVM: selftests: Add back the missing check of MONITOR/MWAIT availability David Woodhouse (1): KVM: x86/xen: Allow 'out of range' event channel ports in IRQ routing table.
