Konstantin Belousov 7e14088d93 Revert back to use int for the page counts. In vn_io_fault(), the i/o 
is chunked to pieces limited by integer io_hold_cnt tunable, while
vm_fault_quick_hold_pages() takes integer max_count as the upper bound.

Rearrange the checks to correctly handle overflowing address arithmetic.
