To help this a bit, the two commits I've seen (there might be others) are
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=52297436199dd
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=7204160eb7809

Of those the former is in Focals 5.4 since Ubuntu-kvm-5.4.0-1036.37
The latter is missing.

Unless the kernel Team says other commits are needed making this too complex maybe a Focal 5.4 kernel with the second commit backported would allo Aaron to test if this commit is enough on his HW?

OTOH the second commit should actually only cache the value, so maybe there are other commits needed anyway, I haven't have more time to look for less obvious commits and the kernel team will be better&faster in doing so anyway.
