mm: use 'unsigned int' for page order
[ Upstream commit d00181b96eb86c914cb327d1de974a1b71366e1b ]
Let's try to be consistent about data type of page order.
[sfr@canb.auug.org.au: fix build (type of pageblock_order)]
[hughd@google.com: some configs end up with MAX_ORDER and pageblock_order having different types]
