Subject[PATCH v2 0/3] Add detailed page size stats in KVM stats
This commit basically adds detailed (large and regular) page size info to
KVM stats and deprecate the old one: lpages.

To support legacy MMU and TDP mmu, we use atomic type for all page stats.

v1 -> v2:
- refactor kvm_update_page_stats and remove 'spte' argument. [sean]
- remove 'lpages' as it can be aggregated by user level [sean]
- fix lpages stats update issue in __handle_change_pte [sean]
- fix style issues and typos. [ben/sean]

pre-v1 (internal reviewers):
- use atomic in all page stats and use 'level' as index. [sean]
- use an extra argument in kvm_update_page_stats for atomic/non-atomic.
- should be careful on the difference between legacy mmu and tdp mmu.

Mingwei Zhang (3):
kvm: mmu/x86: Remove redundant spte present check in mmu_set_spte
KVM: x86/mmu: Avoid collision with !PRESENT SPTEs in TDP MMU lpage
kvm: mmu/x86: Add detailed page size stats
