Shuo A Liu 17bc7f08c9 hv: nested: Create a page pool for shadow EPT construction ... Shadow EPT uses lots of pages to construct the shadow page table. To utilize the memory more efficient, a page poll sept_page_pool is introduced. For simplicity, total platform RAM size is considered to calculate the memory needed for shadow page tables. This is not an accurate upper bound. This can satisfy typical use-cases where there is not a lot of overcommitment and sharing of memory between L2 VMs. Memory of the pool is marked as reserved from E820 table in early stage.
