Thanks for fixing this. I had been reliably hitting that fpu state splat since 5.18-rc1 with fstests, and was annoying because it made a few tests fail (fstests reports a failure whenever there's a splat or warning in dmesg).
I confirm that with this patchset applied the issue no longer happens and everything seems to be working fine, so:
