    Subject[013/146] x86, cpufeature: Fix cpuid leaf 7 feature detection
    2.6.38-stable review patch.  If anyone has any objections, please let us know.

    ------------------

    From: Fenghua Yu <fenghua.yu@intel.com>

    commit 2494b030ba9334c7dd7df9b9f7abe4eacc950ec5 upstream.

    CPUID leaf 7, subleaf 0 returns the maximum subleaf in EAX, not the
    number of subleaves. Since so far only subleaf 0 is defined (and only
    the EBX bitfield) we do not need to qualify the test.
