Here are some more from a 32-bit build here:

fs/exec.c: In function ‘get_user_arg_ptr’:
fs/exec.c:414:6: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
fs/splice.c: In function ‘vmsplice_to_user’:
fs/splice.c:1556:11: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
ipc/syscall.c: In function ‘sys_ipc’:
ipc/syscall.c:39:7: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

Thanks.
