Subject: [PATCH v2 09/25] perf: arm_spe_pmu: Convert to new IRQ affinity retrieval API
Date: Mon, 15 Sep 2025 09:56:46 +0100	[thread overview]
Message-ID: <20250915085702.519996-10-maz@kernel.org> (raw)
In-Reply-To: <20250915085702.519996-1-maz@kernel.org>

Now that the relevant interrupt controllers are equipped with
a callback returning the affinity of per-CPU interrupts, switch
the ARM SPE driver over to this new method.
