    The cache itself isn't broken. Reporting of the size of it is.

    The bug is potentially in all cores with cpuid 670->68F
    If you have it, and you're not running a kernel with the
    fix you'll see you have a 16MB cache. If you run a kernel
    with the fix, you'll have the correct size (64KB)

    arch/i386/kernel/setup.c display_cacheinfo()
