From 9d90a2b98e6e5f793cd0c434f28bb98a1eb22fe0 Mon Sep 17 00:00:00 2001 From: Luiz Capitulino Date: Mon, 28 Nov 2022 17:08:34 +0000 Subject: [PATCH] irqchip/gic-v3: Always trust the managed affinity provided by the core code From: Marc Zyngier commit 3f893a5962d31c0164efdbf6174ed0784f1d7603 upstream. Now that the core code has been fixed to always give us an affinity that only includes online CPUs, directly use this affinity when computing a target CPU.
