instead of the pa. Most callers already had it handy and those who didn't
only called it for managed pages and were outside time-critical code.
This will allow us to make those functions clean and fast on sparc and
sparc64 letting us to avoid unnecessary cache flushes.
deraadt@ miod@ drahn@ ok.

This makes sure it will be regenerated if you run config(8) again.

The only OSes I've seen that use SIZE_T_MAX are 4.4BSD-derived whereas
SYSV things seem to use SIZE_MAX. It is also consistent with SSIZE_MAX
(which we already have). deraadt@ OK

an uvm aobj, copy out the signal trampoline into it and share that page
among all processes for the same emulation.
This also requires us to actually be able to tell signal code where the
trampoline is located, so introduce a new field in struct proc - p_sigcode
that is a pointer to sigcode. This allows us to remove all the ugly
calculations of the signal trampoline address done in every sendsig
function in the tree (that's why so many files are changed).
Tested by various people. ok deraadt@

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.

As a bonus this gets rid of the incorrect gcc 2.95 warnings in machdep.c
