Dear Dave, dear Boris, dear x86 maintainers, as follow-up to the discussion on my initial patch on changing the visibility of X86_FEATURE_NAMES (see Link), here are two patches: Patch 1 simply makes the minimal one-line change to make X86_FEATURE_NAMES disappear from the prompt. Patch 2 is the more radical change to remove the whole config and see which code would generally be impacted; just as quick exploration. The diffstat shows we are getting rid of a bit of code throughout arch/x86, but the change and reduction is not too complex either: arch/x86/Kconfig | 12 ------------ arch/x86/Kconfig.cpu | 2 +- arch/x86/boot/Makefile | 2 -- arch/x86/boot/cpu.c | 13 ------------- arch/x86/include/asm/cpufeature.h | 5 ----- arch/x86/kernel/cpu/Makefile | 4 +--- arch/x86/kernel/cpu/common.c | 4 ---- 7 files changed, 2 insertions(+), 40 deletions(-) Probably, you just want to pick patch 1 and wait for any complaints. Or if you are confident the compliants will not show up, simply apply both. Otherwise, I will put it on my list to come back in a year or two, and if there were no complaints till then, provide the updated patch to remove the X86_FEATURE_NAMES config then.
