in the original hardwired sysctl implementation.
The buf size calculator still overflows an integer on machines with large
KVA (eg: ia64) where the number of pages does not fit into an int. Use
'long' there.
Change Maxmem and physmem and related variables to 'long', mostly for
completeness. Machines are not likely to overflow 'int' pages in the
near term, but then again, 640K ought to be enough for anybody. This
comes for free on 32 bit machines, so why not?

the minimum of either physmem or KVA. But.. btoc() casts the address
to (unsigned int). This is NOT GOOD on 64 bit machines and on alpha and
ia64, this results in a buffer limit of around 500K (not megs). This
causes extreme disk access problems on alpha and ia64. Since this cast
is simply to ensure that it is unsigned, use 'vm_offset_t' instead. This
is available because it is already defined in types.h.
Alpha has been suffering from this for ages. It always felt like the
caching wasn't working, and unfortunately it turned out that way. :-(

Peter and I fried our brains on this for a couple of hours figuring out
what this actually means in the context of multiple threads.

- If either of proc or kse are NULL during thread_exit(), then
the kernel is going to fault because parts of the function
assume they aren't NULL. Instead, just assert they aren't NULL
(as well as the kse group) and assume they are in all of the
code. It doesn't make sense for them to be NULL here anyways.
- Move the PROC_UNLOCK(p) up above clearing td_proc, etc. since
otherwise we will panic if the proc's lock is contested.

this was quite broken, it never was updated for metadata support.
The a.out kld file support was never really used, as it wasn't necessary.
You could always load elf kld's, even in an a.out kernel.

ECONNABORTED. Make this happen in the non-blocking case as well.
The previous behavior was to return EAGAIN, which (a) is not
consistent with the blocking case and (b) causes the application
to think the socket is still valid.

Removed the main part of the pollution. All clients have been converted
to either not depend on getting old locking interfaces from this new
locking header, or usual case to get it from another header (typically
vnode.h, where declaring old loccking interfaces is less bogus because
vnode.h uses them internally).
