Hi Andrew,
After merging the akpm-current tree, today's linux-next build (arm
defconfig) produced these warnings:

Introduced by commit 6e162b4c49f7 ("mem-hotplug: let memblock skip the
hotpluggable memory regions in __next_mem_range()"). The second
argument to memblock_clear_hotplug() is a phys_addr_t, which varies in
size between architectures/platforms.
