Notes:
 carnil> This one seems a bit compliated to track, the commits from the
 carnil> pixel/2021-12-01 are spread over two versions. But it's not
 carnil> very clear to what CVE-2021-39636 is referring to, assuming it
 carnil> is for the pointer leak to userspace?
 bwh> Pretty sure this is about leaking pointers. The last 2 commits
 bwh> are fixing that and the first 3 are dependencies for the fix.
