Merge tag 'kvm-x86-misc-6.7' of https://github.com/kvm-x86/linux into HEAD
KVM x86 misc changes for 6.7:
- Add CONFIG_KVM_MAX_NR_VCPUS to allow supporting up to 4096 vCPUs without
forcing more common use cases to eat the extra memory overhead.
- Add IBPB and SBPB virtualization support.
- Fix a bug where restoring a vCPU snapshot that was taken within 1 second of
creating the original vCPU would cause KVM to try to synchronize the vCPU's
TSC and thus clobber the correct TSC being set by userspace.
- Compute guest wall clock using a single TSC read to avoid generating an
inaccurate time, e.g. if the vCPU is preempted between multiple TSC reads.
- "Virtualize" HWCR.TscFreqSel to make Linux guests happy, which complain
about a "Firmware Bug" if the bit isn't set for select F/M/S combos.
- Don't apply side effects to Hyper-V's synthetic timer on writes from
userspace to fix an issue where the auto-enable behavior can trigger
spurious interrupts, i.e. do auto-enabling only for guest writes.
- Remove an unnecessary kick of all vCPUs when synchronizing the dirty log
without PML enabled.
- Advertise "support" for non-serializing FS/GS base MSR writes as appropriate.
- Use octal notation for file permissions through KVM x86.
- Fix a handful of typo fixes and warts.
