Merge tag 'kvm-x86-misc-6.12' of https://github.com/kvm-x86/linux into HEAD
KVM x86 misc changes for 6.12
- Advertise AVX10.1 to userspace (effectively prep work for the "real" AVX10
functionality that is on the horizon).
- Rework common MSR handling code to suppress errors on userspace accesses to
unsupported-but-advertised MSRs. This will allow removing (almost?) all of
KVM's exemptions for userspace access to MSRs that shouldn't exist based on
the vCPU model (the actual cleanup is non-trivial future work).
- Rework KVM's handling of x2APIC ICR, again, because AMD (x2AVIC) splits the
64-bit value into the legacy ICR and ICR2 storage, whereas Intel (APICv)
stores the entire 64-bit value a the ICR offset.
- Fix a bug where KVM would fail to exit to userspace if one was triggered by
a fastpath exit handler.
- Add fastpath handling of HLT VM-Exit to expedite re-entering the guest when
there's already a pending wake event at the time of the exit.
- Finally fix the RSM vs. nested VM-Enter WARN by forcing the vCPU out of
guest mode prior to signalling SHUTDOWN (architecturally, the SHUTDOWN is
supposed to hit L1, not L2).
