From b8d9884ac6c2c5222ea4a2d23bf9bec613e8eacc Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Fri, 18 Aug 2017 09:39:21 +0100 Subject: [PATCH] irqchip/bcm-7038-l1: Report that effective affinity is a single target The BCM 7038-L1 driver only targets a single CPU at a time, even if the notional affinity is wider. Let's inform the core code about this.
