    LoongArch: Fix probing of the CRC32 feature · df830336
    Huacai Chen authored
    Not all LoongArch processors support CRC32 instructions. This feature
    is indicated by CPUCFG1.CRC32 (Bit25) but it is wrongly defined in the
    previous versions of the ISA manual (and so does in loongarch.h). The
    CRC32 feature is set unconditionally now, so fix it.
    
    BTW, expose the CRC32 feature in /proc/cpuinfo.
