interupt level events. This needs a lot of cleanup, but has been working
here for a month or two.. originally needed for CAM integration

still quite messy in there..
mostly for objects that have the fewest dependencies on `Makefile'

Give an explicit rule for building vnode_if.o. This fixes building
it without ${PROF}.
Use .ORDER instead of a stamp file to avoid building vnode_if.[ch]

Removed explicit dependencies that will be generated by `make' (.c.o)

Added missing dependencies of special objects on opt_global.h.
Use ${NORMAL_C} instead of special rules for special objects where

i386's with 64-bit longs (unnecessary use of 64-bit variables
caused remarkably few problems in C code, but the inline asm here
tended to fail because there are no 64-bit registers). Since the
interfaces here are very machine-dependent and shouldn't be used
outside of the kernel, use a standard types of "known" width instead
of fixed-width types.
Changed all quad_t's to u_int64_t's. quad_t isn't standard, and
using signed types for 64-bit registers was bogus (but made no
difference).
to ensure 32-bit variables. Doing so broke i386's with 64-bit

chars and pointers since the bootinfo struct layout is a binary

16-bit code.
least unsuitable for holding an object pointer. This should have been
used to fix warnings about casts between pointers and ints on alphas.
Moved corresponding existing general typedef (fptrint_t) for function
pointers from the i386 <machine/profile.h> to a kernel-only typedef
in <machine/types.h>. Kludged libc/gmon/mcount.c so that it can
still see this typedef.

syscons. Create a new virtual key like hibernate for suspend. Update
apm_bios.h to define more apm bios goodies.
There is only cdevsw (which should be renamed in a later edit to deventry
or something). cdevsw contains the union of what were in both bdevsw an
cdevsw entries. The bdevsw[] table stiff exists and is a second pointer
to the cdevsw entry of the device. it's major is in d_bmaj rather than
d_maj. some cleanup still to happen (e.g. dsopen now gets two pointers
to the same cdevsw struct instead of one to a bdevsw and one to a cdevsw).
rawread()/rawwrite() went away as part of this though it's not strictly
the same patch, just that it involves all the same lines in the drivers.
cdroms no longer have write() entries (they did have rawwrite (?)).
tapes no longer have support for bdev operations.

Kapok Computer Co. notebook with AMI 'WinBIOS' which seems to insist
on having a short jump and nop as the first instructions in the
boot sector code. The prevailing theory is that the BIOS is doing
some sort of boot sector virus detection and refusing to run any
boot block that doesn't start with the same instruction sequence as
MS-DOG boot sector code. If this is the case, it would be nice if it
actually printed an error message to this effect instead of just
saying 'FAILED.'
This workaround has no effect on the boot sector code other than to
increase its size by three bytes.
code. Apart from the first one, none really affect typical configurations
but are nevertheless unnecessary limitations. We use netbooted PCs as
student X-terminals and all of the below fixes have been useful. Apologies
for including them all in one PR, but some are just too silly or trivial
to send on their own!
a) Newer SMC cards have hardware addresses starting with 00:E0.
Netboot compares the MAC address with 00:00:C0 to determine
if it is a WD/SMC card, so it fails to detect these.
b) Netboot is unable to boot kzipped kernels, as it assumes that
the kernel load address is 0x100000.
c) Users can abort the booting process and enter arbitrary network
addresses, or boot from a floppy disk. This can be a problem when
netbooted machines are used in a student environment.
d) It is not possible to set all options via bootp. For example there
is no way to remotely force a client to boot from disk. With both
SECURE_BOOT(patch below) and NO_TFTP defined, short of unplugging
the eprom there is no way at all to get the client to boot locally.
A generic solution is to allow complete netboot commands to be sent
using bootp lines such as:
:T132="diskboot":
e) The last character of netboot command names is not checked. You
can type 'iz 10.0.0.1' and it will be interpreted as 'ip'. This
is only important if you try to add a new command which is the
same as an existing one except for the last character.
f) We have a configuration where multiple servers are willing to serve
a diskless client. The tftp config file, or the bootptab entry on
each server must specify the root and swap filesystems as 'ip:/fs'
even though 'ip' will usually be the responding server's IP address.
It would be nice if netboot could automatically prepend the server's
IP address to an entry specified as just '/fs', so that multiple
servers can use the same tftp or bootp configuration files. Admittedly
this is hardly a major problem!

The patch supports using the X10 Mouse Remote in both stand-alone and
pass-through configurations, so you can plug your mouse and remote into the
same serial port, use the mouse for X, and use the remote for other apps
like Fxtv. For instance, we can now control fxtv via the remote control
just like a TV : change channels, mute, increase volume, zoom video,
freeze frame 8)
The mouse events are channeled through the syscons/sysmouse I/F like
normal, and the remote buttons are "syphoned off" to a UNIX-domain stream
socket (defined as _PATH_MOUSEREMOTE in <machine/mouse.h>) for a
remote-aware app to grab and use.

- if all sioprobe()s failed, then the console driver followed null

- if the sioprobe() for the console failed but another sioprobe()

- it was silly for the console to not be there after printing boot
