Ingo Molnar e1d9fd2e3d [PATCH] suspend: fix suspend on single-CPU systems 
Clark Williams reported that suspend doesnt work on his laptop on
2.6.20-rc1-rt kernels. The bug was introduced by the following cleanup
commit:

 commit 112cecb2cc
 Author: Siddha, Suresh B <suresh.b.siddha@intel.com>
 Date:   Wed Dec 6 20:34:31 2006 -0800

    [PATCH] suspend: don't change cpus_allowed for task initiating the suspend

because with this change 'error' is not initialized to 0 anymore, if
there are no other online CPUs. (i.e. if the system is single-CPU).

the fix is the initialize it to 0. The really weird thing is that my
version of gcc does not warn about this non-initialized variable
situation ...

(also fix the kernel printk in the error branch, it was missing a
 newline)
