Subject: [PATCH 0/4] KVM: Enable EPT access bit feature

EPT A/D bits enable VMMs to efficiently implement memory management and page classification algorithms to optimize VM memory operations such as de-fragmentation, paging, live-migration, and check-pointing.

The series of patches enable the EPT access bit in KVM.

PATCH 1: Add EPT A/D bits definition.
PATCH 2: Add kernel parameter to control EPT A/D bits support, the feature is on by default.
PATCH 3: Enable EPT A/D bits if supported by turning on relevant bit in EPTP.
PATCH 4: Enabling Access bit when doing memory swapping.
