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

[Sean Christopherson]

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@xxxxxxxxxx

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@xxxxxxxxxx
