    Replace cpuid asm statement with __cpuid_count

    The compiler doesn't know that the cpuid asm statement in intel_check_word
    will trash RBX.  We are lucky that it doesn't cause any problems since
    RBX is also used by compiler for other purposes so that RBX is saved and
    restored.  This patch replaces it with __cpuid_count.

        [BZ #17259]
        * sysdeps/x86_64/cacheinfo.c (intel_check_word): Replace cpuid
        asm statement with __cpuid_count.
