From ff741906ad3cf4b8ca1a958acb013a97a6381ca2 Mon Sep 17 00:00:00 2001 From: Ashok Raj Date: Fri, 11 Nov 2005 14:32:40 -0800 Subject: [IA64] support for cpu0 removal here is the BSP removal support for IA64. Its pretty much the same thing that was released a while back, but has your feedback incorporated. - Removed CONFIG_BSP_REMOVE_WORKAROUND and associated cmdline param - Fixed compile issue with sn2/zx1 due to a undefined fix_b0_for_bsp - some formatting nits (whitespace etc) This has been tested on tiger and long back by alex on hp systems as well.
