would cause a panic.
To do so, instead of panic'ing in pmap_protect() if the pages which are
supposed to be used for the mapping are out of the affordable pmap limits,
just return, and handle this in pmap_enter, by either returning EFAULT if
pmap_enter has been invoked with PMAP_CANFAIL, or panicing there if there
is no escape.

way to discern which one was the boot device.

and return a VM_PAGE. This is to allow sparc64 to cheaply record the
VAC color for those pages.

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.

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@

Some header syncing and a couple network drivers came along for the ride.
Assembly files have been renamed from .s to .S to facilitate diffs.
Kernel is backwards compat - with manual interaction.
OpenBSD features have been preserved.

Tested by various people on various platforms, I'm willing to fix any
breakage this causes.
ok niels@ deraadt@ and mickey@ (after his comments were applied)

we schedule a SIGFPE signal delivery to the faulting process.
However, arithmetic faults come in two flavors: "traps" that are "regular"
exceptions, and "faults" that are restartable exceptions.
In the "fault" case, the frame pc points to the faulting instruction, instead
of the next instruction, in case we could save the world by tweaking memory
and make the instruction not fault again when restarted.
In practice, this led to processes blocked in a SIGFPE loop madness.
To avoid this, add a skip_opcode() routine to compute the address of the
next opcode, effectively skipping the offending instruction ; this routine
is a very stripped-down db_disasm().
While there, enhance the ddb disassembler to correctly recognize and
disassemble two-byte opcodes.

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.
