Since x86-64 and x32 use the same set of sched_XXX system call
interface:
[hjl@gnu-6 linux-stable]$ grep sched_
arch/x86/entry/syscalls/syscall_64.tbl

__cpu_mask should be __syscall_ulong_t.
[BZ #19313]
* sysdeps/unix/sysv/linux/bits/sched.h (__cpu_mask): Replace
unsigned long int with __syscall_ulong_t.
