On 32-bit:
userfaultfd.c: In function 'locking_thread':
userfaultfd.c:152: warning: left shift count >= width of type
userfaultfd.c: In function 'uffd_poll_thread':
userfaultfd.c:295: warning: cast to pointer from integer of different size
userfaultfd.c: In function 'uffd_read_thread':
userfaultfd.c:332: warning: cast to pointer from integer of different size
Fix the shift warning by splitting the shift in two parts, and the
integer/pointer warnigns by adding intermediate casts to "unsigned long".
