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


From: Daniil Tatianin
Subject: [PATCH 0/2] i386/a-b-bootblock: zero the first byte of each page on start
Date: Thu, 7 Sep 2023 22:29:42 +0300

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.
