From c459ce8b5a7d933a3bcf6915ab17ac1e036e2ac4 Mon Sep 17 00:00:00 2001 From: Tony Luck Date: Mon, 29 Sep 2008 16:39:19 -0700 Subject: [IA64] Put the space for cpu0 per-cpu area into .data section Initial fix for making sure that we can access percpu variables in all C code (commit: 10617bbe84628eb18ab5f723d3ba35005adde143) inadvertantly allocated the memory in the "percpu" section of the vmlinux ELF executable. This confused kexec/dump.
