From 8f5ee79c92a6b87abea676fd0b94a10953d181f1 Mon Sep 17 00:00:00 2001 From: Andrew Bresticker Date: Mon, 20 Oct 2014 12:03:56 -0700 Subject: [PATCH] irqchip: mips-gic: Remove gic_{pending,itrmask}_regs 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.
