Sorry. I have checked the manual and it turns out you & Yuli are correct: even though the narrower CRC instructions doesn't require GRLEN=64, they still *aren't* part of LA32 (LoongArch reference manual v1.10, Volume 1, Table 2-1). Counter-intuitive as it is, the original patch is correct nevertheless.
I'm going to amend my review shortly.
