Subject: [PATCH 1/3] percpu: Merge VERIFY_PERCPU_PTR() into its only user
Date: Mon, 21 Oct 2024 10:07:36 +0200	[thread overview]
Message-ID: <20241021080856.48746-1-ubizjak@gmail.com> (raw)

Merge VERIFY_PERCPU_PTR() into non-CONFIG_SMP per_cpu_ptr()
to make macro similar to CONFIG_SMP per_cpu_ptr(). This will
allow a follow-up patch to refactor common code to a macro.

No functional changes, non-CONFIG_SMP per_cpu_ptr() was
the only user of VERIFY_PERCPU_PTR().
