7 * Page-directory addresses above 4GB do not fit into architectural %cr3.
8 * When accessing %cr3, or equivalent field in vcpu_guest_context, guests
9 * must use the following accessor macros to pack/unpack valid MFNs.
10 *
11 * Note that Xen is using the fact that the pagetable base is always
12 * page-aligned, and putting the 12 MSB of the address into the 12 LSB
13 * of cr3.
