KVM: x86/mmu: Avoid reacquiring RCU if TDP MMU fails to allocate an SP (2024-06-14 09:25:03 -0700)
----------------------------------------------------------------
KVM x86 MMU changes for 6.11
- Don't allocate kvm_mmu_page.shadowed_translation for shadow pages that can't
hole leafs SPTEs.
- Unconditionally drop mmu_lock when allocating TDP MMU page tables for eager
page splitting to avoid stalling vCPUs when splitting huge pages.
- Misc cleanups
