Subject: [GIT PULL] KVM: x86: Fixes for 6.16-rcN

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-@google.com

The following changes since commit 28224ef02b56fceee2c161fe2a49a0bb197e44f5:

  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.
