Date: Thu, 06 Aug 2009 18:33:28 +0900 From: Tejun Heo <tj@...nel.org> To: Linux Kernel <linux-kernel@...r.kernel.org>, Ingo Molnar <mingo@...e.hu>, David Miller <davem@...emloft.net>, sparclinux@...r.kernel.org Subject: [PATCH 1/2 2.6.31-rc5 REPOST] init: set nr_cpu_ids before setup_per_cpu_areas() nr_cpu_ids is dependent only on cpu_possible_map and setup_per_cpu_areas() already depends on cpu_possible_map and will use nr_cpu_ids. Initialize nr_cpu_ids before setting up percpu areas. Signed-off-by: Tejun Heo <tj@...nel.org> --- This is repost of the following two patches with sparclinux mailing list cc'd because I couldn't get any response from David Miller. Nothing has changed code-wise. http://thread.gmane.org/gmane.linux.kernel/867587 These two patches fix boot failure on sparc64 which happens if the cpus don't have consecutive cpu numbers.
