When allocating bus space in bus_space_alloc(), use EX_FAST to find
...
the first fit in the map. The previous behavior violated the principle
of least surprise (especially annoying when you're debugging space allocation
problems). Suggested by Chris Demetriou.

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.
these are the changes to the old Mach VM system to allow both to be
available in the kernel.

Allow DELAY() to be called anytime:

-don't enable interrupts at the end of gettick(), restore the previous
state instead
-start timer/counter 0 from delay() if necessary
-comment out "findcpuspeed()", it would clobber the timer again, and it
is unused anyway
