Processor feature human-readable names

modulename: capflags.ko

configname: CONFIG_X86_FEATURE_NAMES

Linux Kernel Configuration
└─>Processor type and features
└─>Processor feature human-readable names
In linux kernel since version 3.18 (release Date: 2014-12-07)
This option compiles in a table of x86 feature bits and corresponding
names. This is required to support /proc/cpuinfo and a few kernel
messages. You can disable this to save space, at the expense of
making those few kernel messages show numeric feature bits instead.

If in doubt, say Y.
