PATCH (2.4.5): /dev/poll support

I think pgp-signing just barfed my last email (typical) so I'm retyping / resending this:

Hi,
this patch adds Solaris 7/8 like /dev/poll support to the kernel.

I can claim no real credit for this as basically this is a fixed version of a patch available from http://www.citi.umich.edu/projects/linux-scalability/
to compile correctly with 2.4.5 that only seemed to work with the 2.3.x devel branch. The reason for this is so I can compile & test an application on my home linux pc when I'm not around my nice work Solaris boxes :)

Please note, I have not got the knowledge of kernel development to know if this patch is broken or badly written. It may be bugged and/or worse than the standard poll() call but my application works so I'll leave profiling etc to people more knowledgable than me.
