Hello list,

Can some of you please review this patchset. The only comment I got on v6 so far
was for a common semaphore header which is merged upstream (and dropped from ARC
port). I'm wating for some more technical feedback before posting v7 (and
hopefully Alistair's sysvipc code is also accepted/merged by that point)

Thx,
-Vineet
