From 2f4cf721eb2ff23b60af2932fd9fa4026f2a1164 Mon Sep 17 00:00:00 2001 From: Jimi Xenidis Date: Thu, 1 Sep 2005 11:57:10 -0400 Subject: [PATCH] [PATCH] ppc64: systemcfg is now a pointer The following patch fixes 2 issues: 1) use PLATFORM_LPAR bit to test if running in LPAR mode 2) systemcfg pointer is assigned from static data in arch/ppc64/kernel/pacaData.c. The file arch/ppc64/kernel/head.S now refers to is using the GOT binding to the pointer and hence must deref it.
