Subject: [PATCH v3 0/3] KVM: x86/mmu: Cleanups from eager page splitting

Eager page splitting cleanups for a few minor things that were noted in
code review but didn't make it into the committed code.

Patch 3 is kinda silly.  If it weren't for the typo, I wouldn't have
bothered (the existing comment is good enough, I couldn't stop tinkering).

v3:
 - Collect more reviews. [David]
 - https://lore.kernel.org/all/20220624213039.2872507-1-seanjc@google.com

v2:
 - Add helper to compute SPTE's index into its parent. [David].
 - Collect reviews [David].
 - Tweak the comment in the last patch after more analysis.

v1:
 - https://lore.kernel.org/all/20220624171808.2845941-1-seanjc@google.com

Sean Christopherson (3):
  KVM: x86/mmu: Add optimized helper to retrieve an SPTE's index
  KVM: x86/mmu: Expand quadrant comment for PG_LEVEL_4K shadow pages
  KVM: x86/mmu: Fix typo and tweak comment for split_desc_cache capacity
