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!

Turned on documented option OVERRIDE_TUNER. LINT is primarily
for turning on options, not for documenting them.
Don't list IPFILTER twice (once as broken).
mmioctl() to fix hundreds of style bugs and a few error handling bugs
(don't check for superuser privilege for inappropriate ioctls, don't
check the input arg for the output-only MEM_RETURNIRQ ioctl, and don't
return EPERM for null changes).
`void *' arg. Fixed or hid most of the resulting type mismatches.
Handlers can now be updated locally (except for reworking their
global declarations in isa_device.h).
Don't generate declarations for isa interrupt handlers at all.
Isa interrupt handlers are now declared in <i386/isa/isa_device.h>
but should be converted take a `void *' arg and staticized as
soon as possible.
Updated CONFIGVERS. New configs are very incompatible with
previous versions.

warnings for a few minutes until config is updated. Interrupt handlers
should never have been configured by config, and the machine generated
declarations get in the way of changing the arg type from int to void *.

Discard events on going-away devices too. Endless loops may have
been possible when an active pccard was removed.

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.
For further info on the X10 Mouse Remote see:

Define an unsigned version of off_t (uoff_t) if KERNEL is defined.
This is useful for micro-optimizing expressions involving off_t's
where you know that the values are non-negative but the compiler
doesn't know it.
Fixed a gratuitous ANSIism.
explicit use of `[unsigned] long long' and `[u]quad_t'.
Fixed disorder of and lack of comments for the types added in the previous
two commits. Improved some comments. The comments should be elswhere
(not duplicated in every MD file).
