18 * the key control system call, 32-bit compatibility version for 64-bit archs
19 * - this should only be called if the 64-bit arch uses weird pointers in
20 * 32-bit mode or doesn't guarantee that the top 32-bits of the argument
21 * registers on taking a 32-bit syscall are zero
22 * - if you can, you should call sys_keyctl directly
