thorpej 872181c2f2 A few changes to make it possible to read UVM histories from userland:
- Protect option headers from inclusion if ! _KERNEL or if _LKM.
- Make sure struct uvm_history is always the same size (not dependent
  on NCPU).
- Add fmtlen and fnlen members to struct uvm_history_ent, which specify
  the lengths fo the fmt and fn strings.
- Add name, namelen, and a list entry to struct uvm_history.
- When a history is initialized, place it on the global list of all histories.

thorpej 90aee42d35 Provide a patchable knob (uvmhist_print_enabled) so that UVM history
buffer printing can be switched on and off at run-time.  Only exists
if the kernel is build with UVMHIST_PRINT, and defaults to `on'.

chs 1f583a43b1 remove locking from UVMCNT counters.
they don't need to be exact, and the locking causes problems
in some of places they're used.

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.  :-)
