    MIPS: Add printing of ISA version in cpuinfo. · a96102be

    Display the MIPS ISA version release in the /proc/cpuinfo file.
    
    [ralf@linux-mips.org: Add support for MIPS I ... IV legacy architecture
    revisions.  Also differenciate between MIPS32 and MIPS64 versions instead
    of lumping them together as just r1 and r2.
    
    Note to application programmers: this indicates the CPU's ISA level
    It does not imply the current execution environment does support it.  For
    example an O32 application seeing "mips64r2" would still be restricted by
    by the execution environment to 32-bit - but the kernel could run mips64r2
    code.  The same for a 32-bit kernel running on a 64-bit processor.  This
    field doesn't include ASEs or optional architecture modules nor other
    detailed flags such as the availability of an FPU.]
