[PATCH] call virt_to_page() with void*, not UL

I'm sure there's a good reason for these functions to take virtual addresses
as unsigned longs, so suppress the warnings and cast them to the proper types
before calling the virt/phys conversion functions

A perfectly acceptable alternative would be to go and change free_pages() to
stop taking unsigned longs for virtual addresses, but this has a much smaller
impact.
