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

fs/exec.c: In function âget_user_arg_ptrâ:
fs/exec.c:414:6: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
fs/splice.c: In function âvmsplice_to_userâ:
fs/splice.c:1556:11: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
ipc/syscall.c: In function âsys_ipcâ:
ipc/syscall.c:39:7: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

Thanks.
