[PATCH] arch-independent syscalls to return long

["Randy.Dunlap" <randy.dunlap@verizon.net>]

[-- Attachment #1: Type: text/plain, Size: 323 bytes --]

Hi,

I posted this about 1 month ago (as [RFC]), to no avail.
However, tonight Andi needs it for pause() [which is failing
on x86_64], and Robert Love mentioned converting the affinity
syscalls.  I had already done them, so here they are again.

Builds and boots.

Please apply.  Patch is to 2.5.65-current.

Thanks,
~Randy
