From c0e9535e1d582ec089c743b705752392fcf3d9a2 Mon Sep 17 00:00:00 2001 From: Igor Guryanov Date: Wed, 24 Dec 2014 16:31:26 +0300 Subject: [PATCH] arc: interrupts - fix mask setup To disable interrupts we need to reset corresponding flags in STATUS32 register. For this we need to OR flags for interrupts level1 and level2 and then AND with current value in STATUS32. Before that implementation was incorrect.
