From 64b5aaad3c743be4f866cfe1ef2c903582e389a3 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Fri, 18 Aug 2017 09:39:22 +0100 Subject: [PATCH] irqchip/metag-ext: Report that effective affinity is a single target The metag-ext driver only targets a single CPU at a time, even if the notional affinity is wider. Let's inform the core code about this.
