Return page size as unsigned long

Browse source 
Currently page_size() returns unsigned int value that is after "bitwise
not" is promoted to unsigned long value e.g. in uffd.c
handle_page_fault. Since the value is unsigned promotion is done with 0
MSB that results in lost of MSB pagefault address bits. So make
page_size to return  unsigned long to avoid such situation.
