KVM: VMX: Combine "check" and "get" APIs for passthrough MSR lookups (2024-02-27 12:29:46 -0800)
----------------------------------------------------------------
KVM VMX changes for 6.9:
- Fix a bug where KVM would report stale/bogus exit qualification information
when exiting to userspace due to an unexpected VM-Exit while the CPU was
vectoring an exception.
- Add a VMX flag in /proc/cpuinfo to report 5-level EPT support.
- Clean up the logic for massaging the passthrough MSR bitmaps when userspace
changes its MSR filter.
