Heiko Carstens 3a6ba4600d [S390] vdso: fix per cpu area allocation 
vdso per cpu area allocation in smp_prepare_cpus() happens with GFP_KERNEL
but irqs disabled. Triggers this one:

Badness at kernel/lockdep.c:2280
Modules linked in:
CPU: 0 Not tainted 2.6.30 #2
Process swapper (pid: 1, task: 000000003fe88000, ksp: 000000003fe87eb8)

Fix this by moving the allocation out of the irqs disabled section.
