Subject: [PATCH v4 4/6] selftests: futex: Add support for 32-bit systems with 64-bit time_t

From: Alistair Francis <alistair.francis@wdc.com>

Using the new __kernel_futex_syscall*() functions let's add support for
32-bit systems with a 64-bit time_t. We can just direclty call the
publically exposed __kernel_futex_syscall_timeout() and
__kernel_futex_syscall_nr_requeue() functions to do this.
