Subject: [GIT PULL] KVM: Fixes for 6.10-rcN

Two selftests fixes and two KVM fixes for 6.10.  Only the kvm_vcpu_on_spin()
fix is tagged for stable@.  I deliberately didn't tag the mmu_notifier issue
for stable@ as I'm 99.9% certain it can't actually cause problems (other than
making UBSAN sad).

Sorry for the late-in-the-week request, I have a feeling I missed your window
where you're working on stuff for this week's KVM pull request.  :-/

  KVM: Stop processing *all* memslots when "null" mmu_notifier handler is found (2024-06-18 08:51:03 -0700)

----------------------------------------------------------------
KVM fixes for 6.10

 - Fix a "shift too big" goof in the KVM_SEV_INIT2 selftest.

 - Compute the max mappable gfn for KVM selftests on x86 using GuestMaxPhyAddr
   from KVM's supported CPUID (if it's available).

 - Fix a race in kvm_vcpu_on_spin() by ensuring loads and stores are atomic.

 - Fix technically benign bug in __kvm_handle_hva_range() where KVM consumes
   the return from a void-returning function as if it were a boolean.
