taking into account swap devices that are in the process of being removed.

manu 2debbde786 Move swapctl(SWAP_STATS) implementation to a separate function called
uvm_swap_stats(). This is done in order to allow COMPAT_* swapctl()
emulation to use it directly without going through sys_swapctl().

The problem with using sys_swapctl() there is that it involves
copying the swapent array to the stackgap, and this array's size
is not known at build time. Hence it would not be possible to
 ensure it would fit in the stackgap in any case.

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.  :-)
