Are there any concerns with merging these into the x86 tree so
that they go upstream for 4.8?  The updates here are pretty
minor.

So I'd love to have some high level MM review & ack for these syscall ABI 
extensions.

That's a quite reasonable request, but I'm really surprised by it at
this point.  The proposed ABI is one very straightforward extension to
one existing system call, plus four others that you personally suggested.

They haven't *changed* since last November:

I see you added Mel and Hugh to the cc.  Is that who you'd like to see
review it?  Is there anyone else?  I'd expect Mel and Hugh's review time
to be highly contended, and I'd rather not gate these on them.

If it helps anyone review these more easily, I've html-ized the affected
manpages and published them:
