Decouple yarrow from random(4) device.

* Make Yarrow an optional kernel component -- enabled by "YARROW_RNG" option.
The files sha2.c, hash.c, randomdev_soft.c and yarrow.c comprise yarrow.

* random(4) device doesn't really depend on rijndael-*. Yarrow, however, does.

* Add random_adaptors.[ch] which is basically a store of random_adaptor's.
random_adaptor is basically an adapter that plugs in to random(4).
random_adaptor can only be plugged in to random(4) very early in bootup.
Unplugging random_adaptor from random(4) is not supported, and is probably a
bad idea anyway, due to potential loss of entropy pools.
We currently have 3 random_adaptors:
+ yarrow
+ rdrand (ivy.c)
+ nehemeiah

* Remove platform dependent logic from probe.c, and move it into
corresponding registration routines of each random_adaptor provider.
probe.c doesn't do anything other than picking a specific random_adaptor
from a list of registered ones.

* If the kernel doesn't have any random_adaptor adapters present then the
creation of /dev/random is postponed until next random_adaptor is kldload'ed.

* Fix randomdev_soft.c to refer to its own random_adaptor, instead of a
system wide one.

Implementation of the upcoming Wireless Mesh standard, 802.11s, on the
net80211 wireless stack. This work is based on the March 2009 D3.0 draft
standard. This standard is expected to become final next year.
This includes two main net80211 modules, ieee80211_mesh.c
which deals with peer link management, link metric calculation,
routing table control and mesh configuration and ieee80211_hwmp.c
which deals with the actually routing process on the mesh network.
HWMP is the mandatory routing protocol on by the mesh standard, but
others, such as RA-OLSR, can be implemented.

Authentication and encryption are not implemented.

There are several scripts under tools/tools/net80211/scripts that can be
used to test different mesh network topologies and they also teach you
how to setup a mesh vap (for the impatient: ifconfig wlan0 create
wlandev ... wlanmode mesh).

A new build option is available: IEEE80211_SUPPORT_MESH and it's enabled
by default on GENERIC kernels for i386, amd64, sparc64 and pc98.

Drivers that support mesh networks right now are: ath, ral and mwl.

Add the uart for 2nd CCU support.

Integrate the new MPSAFE TTY layer to the FreeBSD operating system.

The last half year I've been working on a replacement TTY layer for the
FreeBSD kernel. The new TTY layer was designed to improve the following:

- Improved driver model:

The old TTY layer has a driver model that is not abstract enough to
make it friendly to use. A good example is the output path, where the
device drivers directly access the output buffers. This means that an
in-kernel PPP implementation must always convert network buffers into
TTY buffers.

If a PPP implementation would be built on top of the new TTY layer
(still needs a hooks layer, though), it would allow the PPP
implementation to directly hand the data to the TTY driver.

- Improved hotplugging:

With the old TTY layer, it isn't entirely safe to destroy TTY's from
the system. This implementation has a two-step destructing design,
where the driver first abandons the TTY. After all threads have left
the TTY, the TTY layer calls a routine in the driver, which can be
used to free resources (unit numbers, etc).

The pts(4) driver also implements this feature, which means
posix_openpt() will now return PTY's that are created on the fly.

- Improved performance:

One of the major improvements is the per-TTY mutex, which is expected
to improve scalability when compared to the old Giant locking.
Another change is the unbuffered copying to userspace, which is both
used on TTY device nodes and PTY masters.

Upgrading should be quite straightforward. Unlike previous versions,
existing kernel configuration files do not need to be changed, except
when they reference device drivers that are listed in UPDATING.

Back in the good old days, PC's had random pieces of rock for
frequency generation and what frequency the generated was anyones
guess.

In general the 32.768kHz RTC clock x-tal was the best, because that
was a regular wrist-watch Xtal, whereas the X-tal generating the
ISA bus frequency was much lower quality, often costing as much as
several cents a piece, so it made good sense to check the ISA bus
frequency against the RTC clock.

The other relevant property of those machines, is that they
typically had no more than 16MB RAM.

These days, CPU chips croak if their clocks are not tightly within
specs and all necessary frequencies are derived from the master
crystal by means if PLL's.

Considering that it takes on average 1.5 second to calibrate the
frequency of the i8254 counter, that more likely than not, we will
not actually use the result of the calibration, and as the final
clincher, we seldom use the i8254 for anything besides BEL in
syscons anyway, it has become time to drop the calibration code.

If you need to tell the system what frequency your i8254 runs,
you can do so from the loader using hw.i8254.freq or using the
sysctl kern.timecounter.tc.i8254.frequency.

Temporary disconnect i4bing, i4bisppp and i4bipr from the build for

This is needed because I4B is not locked and NET_NEEDS_GIANT goes away.

Add wlan_scan_ap and wlan_scan_sta to platforms that include wlan.

Use default options for default partitioning schemes, rather than
making the relevant files standard. This avoids duplication and
makes it easier to override/disable unwanted schemes. Since ARM
doesn't have a DEFAULTS configuration file, leave the source
files for the BSD and MBR partitioning schemes in files.arm for
now.

Enable AUDIT by default in the GENERIC kernel, allowing security event
auditing to be turned on without a kernel recompile, just an rc.conf

Approved by: pjd

Evolve the ctlreq interface added to geom_gpt into a generic
partitioning class that supports multiple schemes. Current
schemes supported are APM (Apple Partition Map) and GPT.
Change all GEOM_APPLE anf GEOM_GPT options into GEOM_PART_APM
and GEOM_PART_GPT (resp).

The ctlreq interface supports verbs to create and destroy
partitioning schemes on a disk; to add, delete and modify
partitions; and to commit or undo changes made.

Remove the KDTRACE option again because of the complaints about having
it as a default.

For the record, the KDTRACE option caused _no_ additional source files
to be compiled in; certainly no CDDL source files. All it did was to
allow existing BSD licensed kernel files to include one or more CDDL
header files.

By removing this from DEFAULTS, the onus is on a kernel builder to add
the option to the kernel config, possibly by including GENERIC and
customising from there. It means that DTrace won't be a feature
available in FreeBSD by default, which is the way I intended it to be.

Without this option, you can't load the dtrace module (which contains
the dtrace device and the DTrace framework). This is equivalent to
requiring an option in a kernel config before you can load the linux
emulation module, for example.

I think it is a mistake to have DTrace ported to FreeBSD, but not
to have it available to everyone, all the time. The only exception
to this is the companies which distribute systems with FreeBSD embedded.
Those companies will customise their systems anyway. The KDTRACE
option was intended for them, and only them.

Build in kernel support for loading DTrace modules by default. This
adds the hooks that DTrace modules register with, and adds a few functions
which have the dtrace_ prefix to allow the DTrace FBT (function boundary
trace) provider to avoid tracing because they are called from the DTtrace
probe context.

Unlike other forms of tracing and debug, DTrace support in the kernel
incurs negligible run-time cost.

I think the only reason why anyone wouldn't want to have kernel support
enabled for DTrace would be due to the license (CDDL) under which DTrace
is released.

Remove the KSE option now that it's in DEFAULTS on these arches/machines.

The 'nooption' kernel config entry has to be used to turn KSE off now.
This isn't my preferred way of dealing with this, but I'll defer to
scottl's experience with the io/mem kernel option change and the grief
experienced over that.

Submitted by: scottl@

Add 'options KSE' to the kernel config DEFAULTS on all arches/machines
except sun4v.

This change makes the transition from a default to an option more
transparent and is an attempt to head off all the compliants that are
likely from people who don't read UPDATING, based on experience with
the io/mem change.

Submitted by: scottl@

Make KSE a kernel option, turned on by default in all GENERIC
kernel configs except sun4v (which doesn't process signals properly
with KSE).

Remove COMPAT_43 from GENERIC (and other kernel configs). For amd64 there's
an explicit comment that it's needed for the linuxolator. This is not the
case anymore. For all other architectures there was only a "KEEP THIS".
I'm (and other people too) running a COMPAT_43-less kernel since it's not
necessary anymore for the linuxolator. Roman is running such a kernel for a
for longer time. No problems so far. And I doubt other (newer than ia32
or alpha) architectures really depend on it.

This may result in a small performance increase for some workloads.

If the removal of COMPAT_43 results in a not working program, please
recompile it and all dependencies and try again before reporting a
problem.

The only place where COMPAT_43 is needed (as in: does not compile without
it) is in the (outdated/not usable since too old) svr4 code.

Note: this does not remove the COMPAT_43TTY option.

Make the ISAPNP code optional and only enable it on i386 and pc98 (used

known to exist. For sparc64 this additionally allows to get rid of the
compat shims for in{b,w,l}()/out{b,w,l}() etc and the associated hacks.

Enable a few more things in x86 NOTES to get broader LINT coverage:
- Turn on iwi(4), ipw(4), and ndis(4) on amd64 and i386.
- Turn on ral(4) and ural(4) on i386, pc98, and amd64.

Add the ability to subset the devices that UART pulls in. This allows
the arm to compile without all the extras that don't appear, at least
not in the flavors of ARM I deal with. This helps us save about 100k.

If I've botched the available devices on a platform, please let me
know and I'll correct ASAP.

- Add C-bus and ISA front-ends for le(4) so it can actually replace
lnc(4) on PC98 and i386. The ISA front-end supports the same non-PNP
network cards as lnc(4) did and additionally a couple of PNP ones.
Like lnc(4), the C-bus front-end of le(4) only supports C-NET(98)S
and is untested due to lack of such hardware, but given that's it's
based on the respective lnc(4) and not too different from the ISA
front-end it should be highly likely to work.
- Remove the descriptions of le(4), which where converted from lnc(4),
from sys/i386/conf/NOTES and sys/pc98/conf/NOTES as there's a common
one in sys/conf/NOTES.

- As only the PCI front-end of le(4) is common to all platforms move its
entry to the PCI NICs section so it's in the same spot in all GENERIC
config files.
- Add a note to the description of pcn(4) informing that is has precedence
over le(4).

Rewrite of puc(4). Significant changes are:
o Properly use rman(9) to manage resources. This eliminates the
need to puc-specific hacks to rman. It also allows devinfo(8)
to be used to find out the specific assignment of resources to
serial/parallel ports.
o Compress the PCI device "database" by optimizing for the common
case and to use a procedural interface to handle the exceptions.
The procedural interface also generalizes the need to setup the
hardware (program chipsets, program clock frequencies).
o Eliminate the need for PUC_FASTINTR. Serdev devices are fast by
default and non-serdev devices are handled by the bus.
o Use the serdev I/F to collect interrupt status and to handle
interrupts across ports in priority order.
o Sync the PCI device configuration to include devices found in
NetBSD and not yet merged to FreeBSD.
o Add support for Quatech 2, 4 and 8 port UARTs.

MFi386: revision 1.1215 (add savagedrm).

- Allow duplicate "machine" directives with the same arguments.
- Move existing "machine" directives to DEFAULTS.

Don't enable PUC_FASTINTR by default in the source. Instead, enable it
via the DEFAULTS kernel configs. This allows folks to turn it that option
off in the kernel configs if desired without having to hack the source.
This is especially useful since PUC_FASTINTR hangs the kernel boot on my
ultra60 which has two uart(4) devices hung off of a puc(4) device.

I did not enable PUC_FASTINTR by default on powerpc since powerpc does not
currently allow sharing of INTR_FAST with non-INTR_FAST like the other
archs.

Move the isa, npx, mem and io devices and the PC98 option from GENERIC

Rename the KDB_STOP_NMI kernel option to STOP_NMI and make it apply to all
IPI_STOP IPIs.
- Change the i386 and amd64 MD IPI code to send an NMI if STOP_NMI is
enabled if an attempt is made to send an IPI_STOP IPI. If the kernel
option is enabled, there is also a sysctl to change the behavior at
runtime (debug.stop_cpus_with_nmi which defaults to enabled). This
includes removing stop_cpus_nmi() and making ipi_nmi_selected() a
private function for i386 and amd64.
- Fix ipi_all(), ipi_all_but_self(), and ipi_self() on i386 and amd64 to
properly handle bitmapped IPIs as well as IPI_STOP IPIs when STOP_NMI is
enabled.
- Fix ipi_nmi_handler() to execute the restart function on the first CPU
that is restarted making use of atomic_readandclear() rather than
assuming that the BSP is always included in the set of restarted CPUs.
Also, the NMI handler didn't clear the function pointer meaning that
subsequent stop and restarts could execute the function again.
- Define a new macro HAVE_STOPPEDPCBS on i386 and amd64 to control the use
of stoppedpcbs[] and always enable it for i386 and amd64 instead of
being dependent on KDB_STOP_NMI. It works fine in both the NMI and
non-NMI cases.

Remove the CPU_ENABLE_SSE option from the i386 and pc98 architectures,
as they are already default for I686_CPU for almost 3 years, and
CPU_DISABLE_SSE always disables it. On the other hand, CPU_ENABLE_SSE

This commit has:
- Removed the option from conf/options.*
- Removed the option and comments from MD NOTES files
- Simplified the CPU_ENABLE_SSE ifdef's so they don't
deal with CPU_ENABLE_SSE from kernel configuration. (*)

For most users, this commit should be largely no-op. If you used to
place CPU_ENABLE_SSE into your kernel configuration for some reason,
it is time to remove it.

(*) The ifdef's of CPU_ENABLE_SSE are not removed at this point, since
we need to change it to !defined(CPU_DISABLE_SSE) && defined(I686_CPU),
not just !defined(CPU_DISABLE_SSE), if we really want to do so.

Sort 'bge' correctly.

Take the support for the 8139C+/8169/8169S/8110S chips out of the
rl(4) driver and put it in a new re(4) driver. The re(4) driver shares
the if_rlreg.h file with rl(4) but is a separate module. (Ultimately
I may change this. For now, it's convenient.)

rl(4) has been modified so that it will never attach to an 8139C+
chip, leaving it to re(4) instead. Only re(4) has the PCI IDs to
match the 8169/8169S/8110S gigE chips. if_re.c contains the same
basic code that was originally bolted onto if_rl.c, with the
following updates:

- Added support for jumbo frames. Currently, there seems to be
a limit of approximately 6200 bytes for jumbo frames on transmit.
(This was determined via experimentation.) The 8169S/8110S chips
apparently are limited to 7.5K frames on transmit. This may require
some more work, though the framework to handle jumbo frames on RX
is in place: the re_rxeof() routine will gather up frames than span
multiple 2K clusters into a single mbuf list.

- Fixed bug in re_txeof(): if we reap some of the TX buffers,
but there are still some pending, re-arm the timer before exiting
re_txeof() so that another timeout interrupt will be generated, just
in case re_start() doesn't do it for us.

- Handle the 'link state changed' interrupt

- Fix a detach bug. If re(4) is loaded as a module, and you do
tcpdump -i re0, then you do 'kldunload if_re,' the system will
panic after a few seconds. This happens because ether_ifdetach()
ends up calling the BPF detach code, which notices the interface
is in promiscuous mode and tries to switch promisc mode off while
detaching the BPF listner. This ultimately results in a call
to re_ioctl() (due to SIOCSIFFLAGS), which in turn calls re_init()
to handle the IFF_PROMISC flag change. Unfortunately, calling re_init()
here turns the chip back on and restarts the 1-second timeout loop
that drives re_tick(). By the time the timeout fires, if_re.ko
has been unloaded, which results in a call to invalid code and
blows up the system.

To fix this, I cleared the IFF_UP flag before calling ether_ifdetach(),
which stops the ioctl routine from trying to reset the chip.

- Modified comments in re_rxeof() relating to the difference in
RX descriptor status bit layout between the 8139C+ and the gigE
chips. The layout is different because the frame length field
was expanded from 12 bits to 13, and they got rid of one of the
status bits to make room.

- Add diagnostic code (re_diag()) to test for the case where a user
has installed a broken 32-bit 8169 PCI NIC in a 64-bit slot. Some
NICs have the REQ64# and ACK64# lines connected even though the
board is 32-bit only (in this case, they should be pulled high).
This fools the chip into doing 64-bit DMA transfers even though
there is no 64-bit data path. To detect this, re_diag() puts the
chip into digital loopback mode and sets the receiver to promiscuous
mode, then initiates a single 64-byte packet transmission. The
frame is echoed back to the host, and if the frame contents are
intact, we know DMA is working correctly, otherwise we complain
loudly on the console and abort the device attach. (At the moment,
I don't know of any way to work around the problem other than
physically modifying the board, so until/unless I can think of a
software workaround, this will have do to.)

- Created re(4) man page

- Modified rlphy.c to allow re(4) to attach as well as rl(4).

Note that this code works for the sample 8169/Marvell 88E1000 NIC
that I have, but probably won't work for the 8169S/8110S chips.
RealTek has sent me some sample NICs, but they haven't arrived yet.
I will probably need to add an rlgphy driver to handle the on-board
PHY in the 8169S/8110S (it needs special DSP initialization).

MFi386: revision 1.1079

Implemented "nooption" and "nomakeoption" config(8) tokens.
Fixed memory leak in the "nodevice" option implementation.

Use these instead of sed(1) in MD NOTES.

Use a single makefile (sys/conf/makeLINT.mk) to generate
LINT for all architectures. (Previous versions missed
the LINT dependency on Makefile, and i386 version also
missed the dependency on ${NOTES}.)

Fixed bugs in the previous NOTES conversion using the
"nodevice" token and sed(1):

- i386 LINT lost "device pst".

- pc98 LINT lost SC_*, MAXCONS and KBD_DISABLE_KEYMAP_LOAD
options, and got needless DPT_* options.

- Added nooptions PPC_DEBUG, PPC_PROBE_CHIPSET, KBD_INSTALL_CDEV
to sparc64 LINT so that it has a chance to config(8).

This basically returns us to where we were before.

Move most everything back to a MI NOTES, and use "nodevice" in MD NOTES
Where needed. Use 'sed' for now in place of "nooptions". Add a sparc64

Permits UFS ACLs to be used with the GENERIC kernel. Due to recent

for file systems not explicitly configured for ACLs by the system
administrator. For UFS1, administrators must still recompile their
kernel to add support for extended attributes; for UFS2, it's sufficient
to enable ACLs using tunefs or at mount-time (tunefs preferred for
reliability reasons). UFS2, for a variety of reasons, including
performance and reliability, is the preferred file system for use with
ACLs.

In some order of controlled fashion, the NO_GEOM options will be
removed, architecture by architecture in the coming days.

There are currently three known issues which may force people to
need the NO_GEOM option:

boot0cfg/fdisk:
Tries to update the MBR while it is being used to control
slices. GEOM does not allow this as a direct operation.

SCSI floppy drives:
Appearantly the scsi-da driver return "EBUSY" if no media
is inserted. This is wrong, it should return ENXIO.

PC98:
It is unclear if GEOM correctly recognizes all variants of
PC98 disklabels. (Help Wanted! I have neither docs nor HW)

Add support for the LSI-Logic Fusion/MP architecture.

This is an architecture that present a thing message passing interface

A less grand view is that this is just another way to package SCSI (SPI or
FC) and FC-IP into a one-driver interface set.

This driver support the following hardware:

LSI FC909: Single channel, 1Gbps, Fibre Channel (FC-SCSI only)
LSI FC929: Dual Channel, 1-2Gbps, Fibre Channel (FC-SCSI only)
LSI 53c1020: Single Channel, Ultra4 (320M) (Untested)
LSI 53c1030: Dual Channel, Ultra4 (320M)

Currently it's in fair shape, but expect a lot of changes over the
next few weeks as it stabilizes.

Credits:

The driver is mostly from some folks from Jeff Roberson's company- I've
been slowly migrating it to broader support that I it came to me as.

The hardware used in developing support came from:

unconditionally compile for the i386. You got the runtime checking whether
you wanted it or not. This makes I386_CPU mutually exclusive with the

PC-98 version of ed driver is a statically limited driver.

Pointed out by: haro@tk.kubota.co.jp (Munehiro Matsuda)

Deal with quoted arguments. This hack parser uses whitespace to delimit
fields, not lex/yacc grammar so it is not an exact match but should be
close enough for most cases.
Deal with 'port?', 'irq?' style specifications. These are parsed as
seperate values in lex/yacc in config(8) but tripped up this helper tool.

Use while (<>) instead of while(<STDIN>) so that perl will automagically
deal with filename arguments. It is amazing how much you forget over time.

Thanks to the people that reminded me this. I knew there was an easy way
that didn't involve messing with $argv, filehandles, etc, but just could
not remember - all of my books are on the opposite side of the planet..

- Moved "hint" informations to GENERIC.hints.
- Cosmetic changes.

bs, olpt, pckbd are static limited devices.

Print error messages to stderr, not stdout.

Borrow phk's axe and apply the next stage of config(8)'s evolution.

Use Warner Losh's "hint" driver to decode ascii strings to fill the
resource table at boot time.

config(8) no longer generates an ioconf.c table - ie: the configuration
no longer has to be compiled into the kernel. You can reconfigure your
isa devices with the likes of this at loader(8) time:
set hint.ed.0.port=0x320

userconfig will be rewritten to use this style interface one day and will
move to /boot/userconfig.4th or something like that.

It is still possible to statically compile in a set of hints into a kernel
if you do not wish to use loader(8). See the "hints" directive in GENERIC
as an example.

All device wiring has been moved out of config(8). There is a set of
helper scripts (see i386/conf/gethints.pl, and the same for alpha and pc98)
that extract the 'at isa? port foo irq bar' from the old files and produces
a hints file. If you install this file as /boot/device.hints (and update
/boot/defaults/loader.conf - You can do a build/install in sys/boot) then
loader will load it automatically for you. You can also compile in the
hints directly with: hints "device.hints" as well.

There are a few things that I'm not too happy with yet. Under this scheme,
things like LINT would no longer be useful as "documentation" of settings.
I have renamed this file to 'NOTES' and stored the example hints strings
in it. However... this is not something that config(8) understands, so
there is a script that extracts the build-specific data from the
documentation file (NOTES) to produce a LINT that can be config'ed and
built. A stack of man4 pages will need updating. :-/

Also, since there is no longer a difference between 'device' and
'pseudo-device' I collapsed the two together, and the resulting 'device'
takes a 'number of units' for devices that still have it statically
allocated. eg: 'device fe 4' will compile the fe driver with NFE set
to 4. You can then set hints for 4 units (0 - 3). Also note that
'device fe0' will be interpreted as "zero units of 'fe'" which would be
bad, so there is a config warning for this. This is only needed for
old drivers that still have static limits on numbers of units.
All the statically limited drivers that I could find were marked.

Please exercise EXTREME CAUTION when transitioning!

Put on my asbestos suit and move $mach/conf/*.$mach to conf/*.$mach as
hinted at in the previous config(8) commits. I've spoken about this with
a few people and after the initial suprise wore off they thought it wasn't
a bad idea. The upshot of it is that all the files*, Makefile*, options*
files are all right next to each other in the hope that people making
changes to one set will remember the others.

Note, config(8) looks to sys/conf first, and falls back to sys/$mach/conf
still, so this doesn't stop people working in subdirs for new platforms.
But once it's in the tree it can be moved next to the other files so that
the non-i386 platforms are (hopefully) treated a little better than as if
they were "second class" ports.

This does not change any user editable files. the config program is
still run in the same directory as before, the per-platform files
(GENERIC, LINT etc) are still in the same place.

Back out default debug kernel. The flags revert to historical behaviour.

Requested-by: ache
bde
dg

Modify targets for debug kernels: when -g was specified, make will
now build a debug kernel called kernel.debug, and create a stripped
version called kernel at the same time. The two targets install and
install.debug are otherwise unchanged.

Requested-by: dillon

Update man page accordingly.

Sync with sys/i386/conf/files.i386 revision 1.233.

1. Modify config to issue different code for debugging.
2. Config complains if you use -g:

Debugging is enabled by default, there is no ned to specify the -g option

3. Config warns you if you don't use -s:

Building kernel with full debugging symbols. Do
"config -s BSD" for historic partial symbolic support.
To install the debugging kernel, do make install.debug

(BSD was the name of the config file I used; I print out the same
name).

4. Modify Makefile.i386, Makefile.alpha, Makefile.pc98 and config to
work if a kernel name other than 'kernel' is specified. This is
not absolutely necessary, but useful, and it was relatively easy.
I now have a kernel called /crapshit :-)

5. Modify Makefile.i386, Makefile.alpha, Makefile.pc98 "clean" target
to remove both the debug and normal kernel.

6. Modify all to install the stripped kernel by default and the debug
kernel if you enter "make install.debug".

7. Update version number of Makefiles and config.

- For some old Cyrix CPUs, %cr2 is clobbered by interrupts. This
problem is worked around by using an interrupt gate for the page
fault handler. This code was originally made for NetBSD/pc98 by
Naofumi Honda <honda@kururu.math.sci.hokudai.ac.jp> and has already
been in PC98 tree. Because of this bug, trap_fatal cannot show
correct page fault address if %cr2 is obtained in this function.
Therefore, trap_fatal uses the value from trap() function.
- The trap handler always enables interruption when buggy application
or kernel code has disabled interrupts and then trapped. This code
was prepared by Bruce Evans <bde@FreeBSD.org>.
