From: Yinghai Lu Date: Sun, 15 Feb 2009 10:54:03 +0000 (-0800) Subject: x86: pre init pirq_entries[] X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=3bd25d0fa3ed588a6735b815cb0c146c23888ace;p=openwrt%2Fstaging%2Fblogic.git x86: pre init pirq_entries[] Impact: cleanup set default value early - this allows the removal of a number of dynamic initialization codepaths, and an #ifdef.
