From 8cf10b4bca9e6c61b764d2e4902b7c3052643217 Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Mon, 12 Aug 2013 14:57:12 -0400 Subject: [PATCH] tile: Enable interrupts in do_work_pending() A recent change triggered a WARN_ON that interrupts were disabled, and in fact other architectures enable interrupts uniformly for their related do_work_pending() type code, and all the things we call from this routine appear to expect interrupts to be enabled. So, enable them.
