230876cf26 Merge parts of chs-ubc2 into the trunk: 
* Remove the casts to vaddr_t from the round_page() and trunc_page() macros to
  make them type-generic, which is necessary i.e. to operate on file offsets
  without truncating them.
* In due course, cast pointer arguments to these macros to an appropriate
  integral type (paddr_t, vaddr_t).

Originally done by Chuck Silvers, updated by myself.

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.

fd9aa8fbba Cast the argument to ptoa() to a vaddr_t to prevent an integer overflow 
from occurring on systems with more than 2G of RAM.

e3a5c2451c Check to see if TRUE and FALSE are already defined before blindly 
trying to define them ourselves.

Fixes PRs kern/2813 and misc/7356.

d2397ac5f7 completely remove Mach VM support. all that is left is the all the 
header files as UVM still uses (most of) these.

8f7ee94e13 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.
