+	clearcpuid=BITNUM [X86]
+			Disable CPUID feature X for the kernel. See
+			include/asm-x86/cpufeature.h for the valid bit numbers.
+			Note the Linux specific bits are not necessarily
+			stable over kernel options, but the vendor specific
+			ones should be.
+			Also note that user programs calling CPUID directly
+			or using the feature without checking anything
+			will still see it. This just prevents it from
+			being used by the kernel or shown in /proc/cpuinfo.
+			Also note the kernel might malfunction if you disable
+			some critical bits.
