Subject: Re: [syzbot] [kvm?] KMSAN: uninit-value in em_ret_far

I think it's not entirely correct to test it on the kmsan tree as the
kmsan tree is actually quite old (the last commit was 6 months ago),
which is way earlier than the point of time when the bug was detected
(syzbot found it only in Nov 2023 -- 2 months ago).

The bug was last hit today on the head of the torvalds tree:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/log/?id=9f8413c4a66f2fb776d3dc3c9ed20bf435eb305e
