- After the guest becomes secure, when we handle a page fault of a page
belonging to SVM in HV, send that page to UV via UV_PAGE_IN.
- Whenever a page is unmapped on the HV side, inform UV via UV_PAGE_INVAL.
- Ensure all those routines that walk the secondary page tables of
the guest don't do so in case of secure VM. For secure guest, the
active secondary page tables are in secure memory and the secondary
page tables in HV are freed when guest becomes secure.
