  KVM: x86/mmu: Fix a largely theoretical race in kvm_mmu_track_write() (2024-05-02 07:49:06 -0700)

----------------------------------------------------------------
KVM x86 MMU changes for 6.10:

 - Process TDP MMU SPTEs that are are zapped while holding mmu_lock for read
   after replacing REMOVED_SPTE with '0' and flushing remote TLBs, which allows
   vCPU tasks to repopulate the zapped region while the zapper finishes tearing
   down the old, defunct page tables.

 - Fix a longstanding, likely benign-in-practice race where KVM could fail to
   detect a write from kvm_mmu_track_write() to a shadowed GPTE if the GPTE is
   first page table being shadowed.
