Subject: [PATCH] x86/cpu: Hide and rename static_cpu_has()
Date: Fri, 19 Jun 2026 18:50:41 -0700	[thread overview]
Message-ID: <20260620015041.336288-1-bp@kernel.org> (raw)

From: "Borislav Petkov (AMD)" <bp@alien8.de>

cpu_feature_enabled() is the one to use to test feature flags so hide
the static thing which doesn't pay attention to disabled mask bits
anyway.

Use the following command to do the replacement:

  $ git grep --files-with-matches -w static_cpu_has -- ':(exclude)*cpufeature.h' \
  | xargs sed -i 's/static_cpu_has(/cpu_feature_enabled\(/g'

There should be no functional changes resulting from this.
