The critical piece of information you're missing from the commit message
is that the MSR_IMM instructions take a single u64.
Therefore to use them, you've got to arrange for all callers to provide
a single u64, rather than a split u32 pair.
You definitely caught me on how I was thinking it ;)
Sometimes it is nice to see a change log with a thinking process.
Thanks!
