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. Signed-off-by: Nathan Fontenot <nfont@austin.ibm.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
