Subject: [PATCH 09/19] irqchip: mips-gic: Remove gic_{pending,itrmask}_regs
Date: Mon, 20 Oct 2014 12:03:56 -0700 [thread overview]
Message-ID: <1413831846-32100-10-git-send-email-abrestic@chromium.org> (raw)
In-Reply-To: <1413831846-32100-1-git-send-email-abrestic@chromium.org>
There's no reason for the pending and masked interrupt bitmasks
to be global. Just declare them on the stack in gic_get_int()
since they only consume (256*2)/8 = 64 bytes.
