What ensures this doesn't actually happen?
Nothing.
We have basically three options here:
- Die early (my patch).
- Issue a warning that the critical situation has been detected and hope
for the best by not doing the remap, but probably run into strange
situations when the discrepancy between E820 map and memory usage is
becoming problematic.
- Do the remap like today and die eventually when the relocated page is
used for p2m/m2p translations (no real option).
