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). Link: https://lore.kernel.org/all/0a7d0a9e-c56e-4ee2-a83b-00164a450...@xen0n.name/
Therefore, we could not directly add ARCH_HAS_CRC32 to config LOONGARCH. Thanks, -- WangYuli
