this patch adds signal handling for mips-user (and mipsel also).
However it doesn't implement setup_rt_frame, but it seems it is not used a lot, so the current patch should support the vast majority of applications.

Note that some web servers and other networking programs that you
might want to use depend on setup_rt_frame.

It is used by code which uses queued SIGIO signals for event queuing
(it's the old "scalable I/O" method before epoll replaced it), and
it's also used by code that uses dnotify to check for file changes.  I
think Samba may also use it in conjunction with F_SETLEASE.

Since you seem to be aiming at networking support, I thought to
mention this...

The program I wrote the patch for doesn't use them. But it shouldn't be very hard to add support for setup_rt_frame, I'll try to add it in the coming weeks.
But the current patch can be very useful already :)

Thanks for pointing this.
