H. Peter Anvin (Intel)	841326332b	x86/cpufeatures: Generate the <asm/cpufeaturemasks.h> header based on build config ... Introduce an AWK script to auto-generate the <asm/cpufeaturemasks.h> header with required and disabled feature masks based on <asm/cpufeatures.h> and the current build config. Thus for any CPU feature with a build config, e.g., X86_FRED, simply add: config X86_DISABLED_FEATURE_FRED def_bool y depends on !X86_FRED to arch/x86/Kconfig.cpufeatures, instead of adding a conditional CPU feature disable flag, e.g., DISABLE_FRED. Lastly, the generated required and disabled feature masks will be added to their corresponding feature masks for this particular compile-time configuration.
