Peter Anvin <hpa@xxxxxxxxxxxxxxx> CommitDate: Tue, 17 May 2011 13:36:29 -0700 x86, cpufeature: Fix cpuid leaf 7 feature detection 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.
