code to be compatible with older versions of FreeBSD.

37641f86f1 Consistently use the BSD u_int and u_short instead of the SYSV uint and
ushort.  In most of these files, there was a mixture of both styles and
this change just makes them self-consistent.

e6b31b2814 Don't use pessimal (u_short) types for i/o ports. This is mainly for
completenss.  The pessimization is tiny compared with i/o port slowness
except on very old machines, but code that used signed short types for
i/o ports was unpessimized long ago, and the macro that detected it
recently started working for u_short types too.  Use of bus space
should have made this moot long ago.

0ae911eb0e Gigacommit to improve device-driver source compatibility between
branches:

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.

This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

1dfc2c167f Be consistent about "static" functions: if the function is marked
static in its prototype, mark it static at the definition too.

602660491c Make delay iteration counts a function of hz as the delay period in each
loop is inversly proportional to hz.

This makes things more sane for configurations with hz != 100.

Cosmetic: Make the loops look similar to the loops in digi.c

ef68f6f3c9 Add a digi_delay() function and use it instead of tsleep() when polling
the card for command completion.

digi_delay() uses either tsleep() or DELAY() depending on the value of
``cold''.

38fc52afea Use the PCI port for pci cards, not just for PCIXR cards.
Add the card name to the error message for the first initialisation
failure, giving us more info about what was actually discovered.

to work on a PCI Xem card.

8ad55476a0 Change linker_reference_module() so that it's passed a struct
mod_depend * (which may be NULL).  The only consumer of this
function at the moment is digi_loadmoduledata(), and that passes
a NULL mod_depend *.

In linker_reference_module(), check to see if we've already got
the required module loaded.  If we have, bump the reference count
and return that, otherwise continue the module search as normal.

dc2e474f79 Change the suser() API to take advantage of td_ucred as well as do a
general cleanup of the API.  The entire API now consists of two functions
similar to the pre-KSE API.  The suser() function takes a thread pointer
as its only argument.  The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0.  The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

5596676e6c KSE Milestone 2
Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)

f1ae94cd5c Allow individual ports to use alternate pin settings (swap dsr & cd)
via the new DIGIIO_SETALTPIN ioctl, and allow the port's ALTPIN setting
to be queried via DIGIIO_GETALTPIN.

The initial state and lock devices are normally used to set and/or
lock ALTPIN settings although the device itself may also be used.

ALTPIN settings are applied per-device and apply to both the callin
and callout device at the same time.

d56c2badd6 Add a ``digi'' driver.
This driver supports PCI Xr-based and ISA Xem Digiboard cards.
dgm will go away soon if there are no problems reported.  For now,
configuring dgm into your kernel warns that you should be using
digi.  This driver is probably close to supporting Xi, Xe and Xeve
cards, but I wouldn't expect them to work properly (hardware
donations welcome).

The digi_* pseudo-drivers are not drivers themselves but contain
the BIOS and FEP/OS binaries for various digiboard cards and are
auto-loaded and auto-unloaded by the digi driver at initialisation
time.  They *may* be configured into the kernel, but waste a lot
of space if they are.  They're intended to be left as modules.

The digictl program is (mainly) used to re-initialise cards that
have external port modules attached such as the PC/Xem.
