From 44c4c25e3103d26bee4cc041cbf526e41975055b Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Thu, 19 Oct 2017 10:11:34 +0100 Subject: [PATCH] irqchip/gic-v3-its: Update effective affinity on VPE mapping When setting the affinity of a VPE (either because we map or move it), make sure the effective affinity is correctly reported back to the core kernel.
