x86/cpufeatures: Clean up the X86_FEATURE definitions
cover x86/cpufeatures: Clean up the X86_FEATURE definitions
The addition of the SSE/AVX/AVX512 CPU feature bits made me look at the arch/x86/include/asm/cpufeatures.h file again, and admittedly it got quite messy over the years, so clean it all up.

PATCH 1/3 x86/cpufeatures: Enable new SSE/AVX/AVX512 CPU features
From: Gayatri Kammela <[email protected]>
Add a few new SSE/AVX/AVX512 instruction groups/features for enumeration in /proc/cpuinfo: AVX512_VBMI2, GFNI, VAES, VPCLMULQDQ, AVX512_VNNI, AVX512_BITALG.
CPUID.(EAX=7,ECX=0):ECX[bit 6] AVX512_VBMI2 CPUID.(EAX=7,ECX=0):ECX[bit 8] GFNI CPUID.(EAX=7,ECX=0):ECX[bit 9] VAES
CPUID.(EAX=7,ECX=0):ECX[bit 10] VPCLMULQDQ
CPUID.(EAX=7,ECX=0):ECX[bit 11] AVX512_VNNI
CPUID.(EAX=7,ECX=0):ECX[bit 12] AVX512_BITALG
Detailed information of CPUID bits for these features can be found in the Intel Architecture Instruction Set Extensions and Future Features Programming Interface document (refer to Table 1-1. and Table 1-2.). A copy of this document is available at

PATCH 2/3 x86/cpufeatures: Re-tabulate the X86_FEATURE definitions
In reply to Ingo MolnarOver the years asm/cpufeatures.h has become somewhat of a mess: the original tabulation style was too narrow, while x86 feature names also kept growing in length, creating frequent field width overflows.
Re-tabulate it to make it wider and easier to read/modify. Also harmonize the tabulation of the other defines in this file to match it.

x86/cpufeatures: Re-tabulate the X86_FEATURE definitions
Over the years asm/cpufeatures.h has become somewhat of a mess: the original tabulation style was too narrow, while x86 feature names also kept growing in length, creating frequent field width overflows.
Re-tabulate it to make it wider and easier to read/modify. Also harmonize the tabulation of the other defines in this file to match it.

PATCH 3/3 x86/cpufeatures: Fix various details in the feature definitions
In reply to Ingo MolnarKept this commit separate from the re-tabulation changes, to make the changes easier to review:
- add better explanation for entries with no explanation
- fix/enhance the text of some of the entries
- fix the vertical alignment of some of the feature number definitions
- fix inconsistent capitalization
- ... and lots of other small details
i.e. make it all more of a coherent unit, instead of a patchwork of years of additions.

x86/cpufeatures: Fix various details in the feature definitions
Kept this commit separate from the re-tabulation changes, to make the changes easier to review:
- add better explanation for entries with no explanation
- fix/enhance the text of some of the entries
- fix the vertical alignment of some of the feature number definitions
- fix inconsistent capitalization
- ... and lots of other small details
i.e. make it all more of a coherent unit, instead of a patchwork of years of additions.
