From b6b74d5490c3ad88de503e0c5d44e4820b79b678 Mon Sep 17 00:00:00 2001 From: David Daney Date: Tue, 13 Oct 2009 08:52:28 -0700 Subject: [PATCH] MIPS: Octeon: Use write_{un,}lock_irq{restore,save} to set irq affinity Since the locks are used from interrupt context we need the irqsave/irqrestore versions of the locking functions.
