[POWERPC] Make high hugepage areas preempt safe Checking source for other get_paca()->field preemption dangers found that open_high_hpage_areas does a structure copy into its paca while preemption is enabled: unsafe however gcc accomplishes it. Just remove that copy: it's done safely afterwards by on_each_cpu, as in open_low_hpage_areas.
