Sorry, but this is wrong. epoll_pwait manipulates the sigmask,
which is about the only thing that we can't let the SPU fiddle
with, so it should be COMPAT_SYS().
I just noticed the move_pages syscall that was added recently,
and that one should indeed be callable from an SPU.
This reminds me that I need to update the comment about what
calls are allowed from the SPU and which ones are not, since
we can now also allow optional ones like the mq_open mentioned
in the comment.
