From c0cfbe6941085f2ebd58e645c10f8836b6d28fe9 Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Thu, 30 Mar 2017 12:06:09 -0700 Subject: [PATCH] irqchip: mips-cpu: Replace magic 0x100 with IE_SW0 Replace use of the magic number 0x100 (ie. bit 8) with the more explanatory IE_SW0 (ie. interrupt enable for software interrupt 0) or C_SW0 (ie. cause bit for software interrupt 0) as appropriate.
