[PATCH v1 0/2] i386/a-b-bootblock: zero the first byte of each page on start

[Daniil Tatianin]

This series fixes an issue where the outcome of the migration qtest
relies on the initial memory contents all being the same across the
first 100MiB of RAM, which is a very fragile invariant.

We fix this by making sure we zero the first byte of every testable page
in range beforehand.
