From 9ec4fa271faf2db3b8e1419c998da1ca6b094eb6 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Mon, 27 Apr 2009 17:57:18 -0700 Subject: irq, cpumask: correct CPUMASKS_OFFSTACK typo and fix fallout CPUMASKS_OFFSTACK is not defined anywhere (it is CPUMASK_OFFSTACK). It is a typo and init_allocate_desc_masks() is called before it set affinity to all cpus... Split init_alloc_desc_masks() into all_desc_masks() and init_desc_masks(). Also use CPUMASK_OFFSTACK in alloc_desc_masks().
