Merge tag 'kvm-x86-pvclock-6.15' of https://github.com/kvm-x86/linux into HEAD
KVM PV clock changes for 6.15:
- Don't take kvm->lock when iterating over vCPUs in the suspend notifier to
fix a largely theoretical deadlock.
- Use the vCPU's actual Xen PV clock information when starting the Xen timer,
as the cached state in arch.hv_clock can be stale/bogus.
- Fix a bug where KVM could bleed PVCLOCK_GUEST_STOPPED across different
PV clocks.
- Restrict PVCLOCK_GUEST_STOPPED to kvmclock, as KVM's suspend notifier only
accounts for kvmclock, and there's no evidence that the flag is actually
supported by Xen guests.
- Clean up the per-vCPU "cache" of its reference pvclock, and instead only
track the vCPU's TSC scaling (multipler+shift) metadata (which is moderately
expensive to compute, and rarely changes for modern setups).
