that specifies which printf funciton it should use. Implement
db_stack_trace_cmd in MI code.
Thanks to miod@ for all the tests.

Tested by various people on various platforms, I'm willing to fix any
breakage this causes.

- update and fix comments
- clean the batc code (still not used by default)
- there was some KNF left to do
- fix incorrect locking behaviour in pmap_remove_all()
- fix incorrect pmap_remove_range() call which would cause the kernel to
enter an infinite loop sometimes at shutdown
- fix an off-by-one page loop in pmap_protect()
This should bring the extra bits of stability I need to resume working on the
compiler...

type characteristics.
internal_types.h will contain only settings invisible from standard C, e.g.,
in the __* or _[A-Z]* namespace, and be reused by files like limits.h.
This allows us to shorten machine/limits.h greatly, as all the common defines
are now in sys/limits.h, plus a small stub in internal_types.h.
Tested on all arches as far as I know.
Approved after discussion with art, millert, deraadt, and others.

your kernel configuration file.
By default, GENERIC will enable this.
When PTRACE is not enabled, several ptrace-like features of the procfs
filesystem will be disabled as well (namely, the ability to read and write
any process' registers, as well as attching, single stepping and detaching
to/from processes).
This should help paranoid people build better sandboxens, and us to build
smaller ramdisks.

The patch allows you to change the value of NMBCLUSTERS, BUFCACHEPERCENT
and NKMEMPAGES using the config command, instead of recompiling the kernel.
This is the kernel part of the patch. I have compiled it on i386, sparc64,
alpha and macppc. -moj ok art@ maja@

- do not do some paranoid sanity checks unless #ifdef DIAGNOSTIC
- remove some of the less-usefull, most screen-eating debug information
- and fix a few typos in the process.
This pmap is slowly starting to have a decent looking shape... Really.

well (not at all) with shortages of the vm_map where the pages are mapped
(usually kmem_map).
Try to deal with it:
- group all information the backend allocator for a pool in a separate
struct. The pool will only have a pointer to that struct.
- change the pool_init API to reflect that.
- link all pools allocating from the same allocator on a linked list.
- Since an allocator is responsible to wait for physical memory it will
only fail (waitok) when it runs out of its backing vm_map, carefully
drain pools using the same allocator so that va space is freed.
(see comments in code for caveats and details).
- change pool_reclaim to return if it actually succeeded to free some
memory, use that information to make draining easier and more efficient.
- get rid of PR_URGENT, noone uses it.

- reorganize the execution flow to be shorter if no device interrupt handler
are registered
- minor style/KNF changes as well

to use constant bitmasks instead of bitfields.
- remove unnecessary (as long as we are not running SMP) locks on the
physsegs.
- update the pmap code to take these changes into account, and gratuitously
change several names and code paths to be closer to existing m68k pmaps. It's
a bit faster now.
- change pmap.c's usage of vm_{offset,size}_t to {p,v}{addr,size}_t.
- remove dead or unused stuff from pmap.c, fix typos, etc
Tested on 187 and 188, should not make things worse for 197.
