If you order the "support order-1 folios" patch first, you can drop
these two lines.

I'm not sure if you need this, but it should return unsigned long, not
unsigned int. With 64KiB pages on Arm, a PMD page is 512MiB (order 13)
and a PUD page will be order 26, which is far too close to 2^32 for
my comfort.
