Hi,

I've just smacked the last obvious places where the CPU ID type was
smaller than an int (signed) and NOCPU is now -1.

We don't have any obvious hardware support for anything with > 254
logical CPUs just at the moment but I'm sure that during the lifecycle
of 11 we're going to start seeing devices with > 254 logical CPUs. I'd
like to try and find / squish any remaining code in /usr/src that uses
a different type for CPU identification.

I'd really appreciate any help I can get in updating things sooner
rather than later. If there are any other ABI related changes I'd like
to get them into -HEAD far before the release point so things can
shake out.

So, this is a call for help. I'm doing this (mostly) in my spare time
with donated hardware, so I'm thankful for any other help people can
provide before 11-REL is cut.

Thanks!
