thorpej eb9cbbe294 Add some very simple code to auto-size the kmem_map. We take the 
amount of physical memory, divide it by 4, and then allow machine
dependent code to place upper and lower bounds on the size.  Export
the computed value to userspace via the new "vm.nkmempages" sysctl.

NKMEMCLUSTERS is now deprecated and will generate an error if you
attempt to use it.  The new option, should you choose to use it,
is called NKMEMPAGES, and two new options NKMEMPAGES_MIN and
NKMEMPAGES_MAX allow the user to configure the bounds in the kernel
config file.

thorpej ea8fb3e04a Turn the proclist lock into a read/write spinlock. Update proclist locking 
calls to reflect this.  Also, block statclock rather than softclock during
in the proclist locking functions, to address a problem reported on
current-users by Sean Doran.

thorpej 3f176180d5 Garbage collect thread_sleep()/thread_wakeup() left over from the old 
Mach VM code.  Also nuke iprintf(), which was no longer used anywhere.

Add proclist locking where appropriate.

mrg f2caacc717 initial import of the new virtual memory system, UVM, into -current. 
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the UVM kernel code portion.


this will be KNF'd shortly.  :-)
