Our 32-bit userspace will see different values for this depending on
running a 32-bit kernel or 64-bit. That last sem_ctime should probably
have a padding so our 32-bit userspace sees the right thing all the
time.

Something like?

---
#ifndef __LP64__
	unsigned int	__pad3;
#endif
	__kernel_time_t sem_ctime;
