From b0a88ae50220b60d6e9686fc5f5a200151217037 Mon Sep 17 00:00:00 2001 From: Jeffrey Deans Date: Thu, 17 Jul 2014 09:20:55 +0100 Subject: [PATCH] MIPS: GIC: Remove GIC_FLAG_IPI MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit irq-gic.c:gic_get_int() masks out interrupts from the pending set which aren’t in the pcpu_mask. Only interrupts marked with GIC_FLAG_IPI were set in pcpu_mask, meaning that peripheral interrupts also had to be marked as IPIs. Remove the use of GIC_FLAG_IPI and allow the flags member of struct gic_intr_map to be zero.
