Subject: [PATCH v2 3/5] powerpc: perf: Use perf_arch_instruction_pointer()
Date: Wed, 11 Sep 2024 22:24:30 +0000 [thread overview]
Message-ID: <20240911222433.3415301-4-coltonlewis@google.com> (raw)
In-Reply-To: <20240911222433.3415301-1-coltonlewis@google.com>
Make sure powerpc uses the arch-specific function now that those have
been reorganized.
