| |
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@kernel.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.
Thanks.
