From 569f75bd02d20043c4baf9fc38d937f37e7572b0 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Wed, 13 Jul 2005 18:20:33 +0000 Subject: [PATCH] Use an irq_enable_hazard hazard barrier in unmask_mips_irq. This hasn't been an actual bug, so it's more a change to be 100% compliant with the requirements of the architecture spec. Similar fix to mask_mips_irq where there was a slightly less theoretical chance of getting hit.
