Junaid Shahid f160c7b7bb kvm: x86: mmu: Lockless access tracking for Intel CPUs without EPT A bits.
This change implements lockless access tracking for Intel CPUs without EPT
A bits. This is achieved by marking the PTEs as not-present (but not
completely clearing them) when clear_flush_young() is called after marking
the pages as accessed. When an EPT Violation is generated as a result of
the VM accessing those pages, the PTEs are restored to their original values.
