[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.
