Eliminate track_modified_needed(), better known as pmap_track_modified()
on other platforms. We no longer need it because we do not create managed
mappings within the clean submap.
- Fix bugs where the value of arithmetic expansion$((...)) was trucated
to type int.
- Change the type used for arithmetic expansion to intmax_t (ie. 64 bit on all
currently supported FreeBSD architectures). SUSv3 requires at least type
long but allows for larger types. Other shells (eg. bash, zsh, NetBSD's sh)
do that too.

Add support files for compiling with soft-float. This has been
copied from ARM and modified to warrant the duplication. Oh,
and to make it work for PowerPC :-)
Remove mfsvr():
o The function is defined unconditionally but depends on SPR_SVR,
which is defined conditionally.
o spr.h defines mfspr() and mtspr(), which is no worse to use.
When writing trailers in sendfile(2), don't call kern_writev()
while holding the socket buffer lock. These leads to an
immediate panic due to recursing the socket buffer lock. This
bug was introduced in uipc_syscalls.c:1.240, but masked by
another bug until that was fixed in uipc_syscalls.c:1.269.
Note that the current fix isn't perfect, but better than
panicking: normally we guarantee that simultaneous invocations
of a system call to write on a stream socket won't be
interlaced, which is ensured by use of the socket buffer sleep
lock. This is guaranteed for the sendfile headers, but not
trailers. In practice, this is likely not a problem, but
should be fixed.

Add a breif example for the wlan change. Include an explicit pointer
to rc.conf(5) to remind people where to look for all the details.
People without network connectivity forget basics like this... This
is in keeping with historic UPDATING entries which try to provide
basic information in the entry, and a pointer to more extensive
information documenting the new thing.
MFamd64 revision 1.544/i386 revision 1.549
Retire pmap_track_modified(). We no longer need it because we do not
create managed mappings within the clean submap. To prevent regressions,
add assertions blocking the creation of managed mappings within the clean
submap.
With rev 1.24 of sys/powerpc/powermac/macio.c, we now get a
total of 6 interrupt resources for scc(4) on macio(4). This
is 3 per channel, of which the 1st of each channel is the
interrupt associated with the SCC. The other 2 are for DMA
operation.
Change scc_bfe_attach() to accept an argument that's the
number of interrupts per channel (ipc) and change each bus
front-end (bfe) to pass that argument through a wrapper
for the device_attach method.
For now, we only allocate the 1st interrupt of each channel
to perserve behaviour.
Take into account the size of the interrupt cell. It's determined
by the parent for interrupt resources. This corrects parsing of
the interrupts property.
With parsing of the property fixed, add all interrupts to the
resource list. Bump the max. number of interrupts from 5 to 6
as scc(4) attached to macio(4) has 6 interrupts (3 per channel).
Introduce a dedicated file for MPC85xx-specific routines. Move cpu_reset()
there, as it's not relevant to Book-E specification, but is an implementation
detail, directly dependent on the given SoC version.

Remove the MD isa_irq_pending() and the underlying PCI-specific
infrastructure. Its only consumer ever was sio(4) and thus was
unused on sparc64 since removing the last traces of sio(4) in
sparc64 configuration files in favor for uart(4) over three
years ago. If similar functionality is required again it should
be brought back as an MD intr_pending() which works for all
busses by using for example interrupt controller hooks.

* Add FreeBSD action extensions.
* Get the kernel module file name rather than hard-coding it like on Solaris.
* Use FreeBSD's process library API.
* Handle FreeBSD's different lock types.
* Get the list of loaded providers via a syscall.
* Use FreeBSD's process library instead of the Solaris one.
* There are a few placeholders in here for which there isn't libproc
support code yet. This is relevent to userland tracing. This set of
commits is designed to get kernel tracing up and running, with the
userland stuff to follow later.
* Add a couple of action definitions for FreeBSD extensions.
* Handle the different ioctl design.
* Add support for the get and set error location.
* Add support for freopen().
There are many places in libdtrace where errno can be set. When an
error is returned all the way back to the dtrace app, it's hard to
figure out where that error came from.
Add a couple of functions to get and set the error location which can
be optionally compiled into the library.
* Make this file compile cleanly.
* Use FreeBSD's kld syscalls to get kernel module information instead
of using an object file system like Solaris uses.
* Get the maximum number of CPUs via a sysctl.
* Handle the different ioctl design.
* Support the freopen() changes.
* Use functions in FreeBSD's process library rather than the CDDL
library that Solaris has which sits on top of their process file
system and is therefore unsuitable for use on FreeBSD. The libproc
API for FreeBSD is deliberately different to that on Solaris because
Sun wouldn't release the libproc.h header under a BSD license.
* Define YY_INPUT for flex since input() can't be re-defined.
* On FreeBSD define both LITTLE_ENDIAN and BIG_ENDIAN and then set the
BYTE_ORDER to the one we are using. On Solaris they define one or
the other but not both. For us to keep using FreeBSD header files,
we need to use endian definitions the same way we do in pure BSD
code.
* Fix a function prototype.
* Allow for the different level of indirection between SYSV's ioctl and BSD's.
* Map a couple of sysconf definitions to one that FreeBSD has.
Solaris has code which makes zlib optional, so they have to jump through
some hoops to get the compression functions. On FreeBSD have libz and
can just link against it.
We need to be consistent with prototype definitions. It isn't OK to
use 'const' and just override it whenever we feel like it. If we use
it at all, then we need to do it properly.
Add a couple of functions that were useful in getting this code ported.
* Set the path to perl on FreeBSD.
* Use the FreeBSD shell.
* On FreeBSD the tests run from the OBJDIR, so output files go there
rather than in the source tree like they do on Solaris.
* FreeBSD doesn't need a special path to the compiler.
Have the man page catch up with the namespace pollution cleanup that
occurred between 2001-2003. Thanks to bde for the history lesson[1]
concerning sys/types.h and the many system calls that at one time

Vendor import of the full userland contrib part of DTrace support from
OpenSolaris. This commit resets files to match the versions in the
OpenSolaris tree as of 2008/04/10.
The changes in this import from the previous import are the ones that
will subsequently re-applied to take files off the vendor branch. This
is unfortunately necessary because the Solaris developers won't allow
FreeBSD support #ifdefs in their source code because that creates
'dead code' (stuff that they never compile).
Replace the prototype vaps_<ifn> and vap_create_<ifn> variables with
more wlans_<ifn> and create_args_<ifn>
Add documentation for these variants and generally update the wireless
device example.
There is are very short lived shim from vaps_<ifn> which produces
a warning and vap_create_<ifn> which does not. Misuse the MFC
notification service to remind me to remove them.
Second, the issue on building modules since the static kernel
build changes is now resolved. I was not able to get the fancier
directory hierarchy working, but this works, both em and igb
build as modules now.
Third, there is now support in em for two new NICs, Hartwell
(or 82574) is a low cost PCIE dual port adapter that has MSIX,
for this release it uses 3 vectors only, RX, TX, and LINK. In
the next release I will add a second TX and RX queue. Also, there
is support here for ICH10, the followon to ICH9. Both of these are
early releases, general availability will follow soon.
Fourth: On Hartwell and ICH10 we now have IEEE 1588 PTP support,
I have implemented this in a provisional way so that early adopters
may try and comment on the functionality. The IOCTL structure may
change. This feature is off by default, you need to edit the Makefile
and add the EM_TIMESYNC define to get the code.

Add "ddb capture print" and "ddb capture status" commands do ddb(8),
alowing the DDB output capture buffer to be easily extracted from
user space. Both of these commands include -M/-N arguments, allowing
them to be used with kernel crash dumps (or /dev/mem).
This makes it easier to use DDB scripting and output capture with
minidumps or full dumps rather than with text dumps, allowing DDB
output (scripted or otherwise) to be easily extracted from a crash
dump.
