Hi,
Are these corrections just AMD64 ? Or does it fix it on i386 as well ?

The Special Note in the advisory discusses this:

Special Note: Speculative execution vulnerability mitigation is a work
in progress. This advisory addresses the most significant
issues for FreeBSD 11.1 on amd64 CPUs. We expect to update
this advisory to include 10.x for amd64 CPUs. Future
FreeBSD
releases will address this issue on i386 and other CPUs.
freebsd-update will include changes on i386 as part of this
update due to common code changes shared between amd64 and
i386, however it contains no functional changes for i386 (in
particular, it does not mitigate the issue on i386).

Sorry about that, my old person eyes missed over that section twice
somehow :(

AMD64 only. This was noted in a "Special Note" rather than the more
typical locations in the advisory.
