Subject: [PATCH v2 15/26] irqchip: mips-cpu: Replace magic 0x100 with IE_SW0
Date: Tue, 30 Aug 2016 18:29:18 +0100 [thread overview]
Message-ID: <20160830172929.16948-16-paul.burton@imgtec.com> (raw)
In-Reply-To: <20160830172929.16948-1-paul.burton@imgtec.com>
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.
