powerpc: Oops in pseries_lmb_remove()
Testing hotplug memory remove has revealed that we can oops in
pseries_lmb_remove(). The incorrect shift causes a NULL pointer
dereference in the page_zone() inline routine.
I have only been able to reproduce the oops on kernels with large pages
enabled.
Tested on Power5 and Power6 with and without large pages enabled.
