This file is built twice: for early 32b mode without paging to measure
MBI and for 64b code to measure dom0 kernel and initramfs. Since MBI
is small, the first case uses TPM to do the hashing. Kernel and
initramfs on the other hand

In preparation for TXT SENTER call, GRUB had to modify MTRR settings

from SLRT where they were saved by the bootloader.

The tests validate that important parts of memory are protected against
DMA attacks, including Xen and MBI. Modules can be tested later, when it
is possible to report issues to a user before invoking TXT reset.

In addition to checking the return values, a bit of extra
