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.
[bgardon]
- should be careful on the difference between legacy mmu and tdp mmu.
