Fix for XSA-240 conflicts with shadow paging
ISSUE DESCRIPTION The fix for XSA-240 introduced a new field into the control structure associated with each page of RAM. This field was added to a union, another member of which is used when Xen uses shadow paging for the guest. During migration, or with the L1TF XSA-273 mitigation for PV guests...

Xen - Pagetable De-typing Unbounded Recursion
Xen - Pagetable De-typing Unbounded Recursion Xen allows pagetables of the same level to map each other as readonly in PV domains. This is useful if a guest wants to use the self-referential pagetable trick for easy access to pagetables by mapped virtual address. When cleaning up a pagetable afte...
x86: Incorrect handling of self-linear shadow mappings with translated guests
ISSUE DESCRIPTION The shadow pagetable code uses linear mappings to inspect and modify the shadow pagetables. A linear mapping which points back to itself is known as self-linear. For translated guests, the shadow linear mappings being in a separate address space are not intended to be self-linea...
