FreeBSD/alpha. The most significant item is to change the command
argument to ioctl functions from int to u_long. This change brings us
inline with various other BSD versions. Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.
The prototype FreeBSD/alpha machdep will follow in a couple of days
time.
Change the definition of a buffer queue so that bufqdisksort can
properly deal with bordered writes.
Add inline functions for accessing buffer queues. This should be
considered an opaque data structure by clients.
callout.h:
New callout implementation.
device.h:
Add support for CAM interrupts.
disk.h:
disklabel.h:
tqdisksort->bufqdisksort
kernel.h:
Add new configuration entries for configuration hooks and calling
cpu_rootconf and cpu_dumpconf.
param.h:
Add a priority for sleeping waiting on config hooks.
proc.h:
Update for new callout implementation.
queue.h:
Add TAILQ_HEAD_INITIALIZER from NetBSD.
systm.h:
Add prototypes for cpu_root/dumpconf, splcam, splsoftcam, etc..
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
- don't include <sys/ioctl.h> in any header. Include <sys/ioccom.h>
instead. This was already done in 4.4Lite for the most important
ioctl headers. Header spam currently increases kernel build
times by 10-20%. There are more than 30000 #includes (not counting
duplicates) for compiling LINT.
- include <sys/types.h> if and only it is necessary to make the header
almost self-sufficient (some ioctl headers still need structs from
elsewhere).
- uniformized idempotency ifdefs. Copied the style in the 4.4Lite
ioctl headers.
It is needed for implementation details but very little of it is
needed for the interface. Include it in the few places that didn't
already include it.
Include <sys/ioccom.h> in <sys/disklabel.h> (as already in
<sys/diskslice.h>) so that all the disk-related headers are almost
self-sufficient.
All new code is "#ifdef PC98"ed so this should make no difference to
PC/AT (and its clones) users.

Prepare for disk slices - more macros for handling disk device numbers,
version of readdisklabel() without DOS goop.
Clean up prototypes.
Uniformize idempotency ifdef.
diskslice.h:
New file.
dkbad.h:
Define more magic numbers.
Declare internalized version of dkbad struct and functions to operate on it.
Uniformize idempotency ifdef.
