[PATCH 1/3] x86/cpu: Remove some macros about feature names
From: Brendan Jackman
Date: Mon Mar 03 2025 - 10:46:31 EST
These macros used to abstract over CONFIG_X86_FEATURE_NAMES, but that
was removed in commit 7583e8fbdc49 ("x86/cpu: Remove
X86_FEATURE_NAMES"). Now they are just unnecessary indirection, remove
them.
