Hi all, I have just committed to tip:x86/cpu the following patch series: H. Peter Anvin (3): x86: generate names for /proc/cpuinfo from x86: cpufeature: add Intel features from CPUID and AVX specs x86: : clean up overlong lines, whitespace The combined patch is below. This changes the CPU feature naming code so that all that information comes from . In the past we have had a number of problems with cpufeature.h diverging from what /proc/cpuinfo showed (not to mention that at one point we would show different things for 32 and 64 bits.) I'm flagging this especially, since this is a patch fairly likely to conflict with other changes (incluing in other trees), although hopefully in a trivial fashion (this patchset should supercede) since I have gone through all the Intel and AMD documentation I could find and made sure it has the flags. It is definitely unfortunate how the kernel sources and /proc/cpuinfo use different names for features; given that we can't change /proc/cpuinfo it might be worthwhile to run a sed script over the kernel sources. -hpa
