regarding apm to LINT
- Disabled the statistics clock on machines which have an APM BIOS and
have the options "APM_BROKEN_STATCLOCK" enabled (which is default
in GENERIC now)
- move around some of the code in clock.c dealing with the rtc to make
it more obvios the effects of disabling the statistics clock

common labels for LINT. There are still some common declarations for the
!KERNEL case in tcp_debug.h and spx_debug.h. trpt depends on the ones in
tcp_debug.h.
Clarified GUS DMA Settings.
Other misc. changes.
This should hold us over until I can finish cleaning up TASD, and finish
reintegrating all of the FreeBSD changes to the sound driver. At that time
this document will be removed, and it's information moved to the handbook.
channel at the same time. The functions isa_dma_acquire() and
isa_dma_release() should be used in all ISA drivers which call isa_dmastart().
This can be used more generally to register the usage of DMA channels in
any driver, but it is required for drivers using isa_dmastart() and friends.
Clean up sanity checks, error messages, etc.
Remove isa_dmadone_nobounce(), it is no longer needed

They don't have BUSY de-asserted by the time they ACK (and thus cause
an interrupt). The workaround is to try seeing if the BUSY will be
de-asserted soon, and if not, to use an incremental backoff and
semi-polled mode instead of the fixed timeout with 1/2 s we've been
using previously (that caused the printer to run really slooow).
Printers that have been working previously should not be affected by
this.
Always delay using one inb(0x84) after each i/o in rtcin() - don't
do this conditional on the bogus option DUMMY_NOPS not being defined.
If you want an optionally slightly faster rtcin() again, then inline
it and use a better named option or sysctl variable. It only needs
to be fast in rtcintr().
Added scsi control devices.
Converted almost everything that I changed to use devfs_add_devswf()
and verbose id macros.
st.c:
Renamed enrst* to erst* since that's what the current name is (enrst
seems to be an old name).
determine if the interface had been assigned an IP address.
This code prevented the interface from receiving ethernet
broadcasts if it had no IP address assigned, and appeared
to be an optimization that is not completely needed.
Add support for LKM operation.
Change M_NOWAIT on buffer memory allocation to M_WAIT in hopes we'll be
able to get ourselves a nice fat buffer from the kernel if we suspend.
Note: The LKM support looks kinda screwy in two areas, where I found
problems with the kernel proper. First, calling dev_attach()
at module load time will cause a panic. I haven't investigated.
Secondly, I had to manually call qcam_drvinit() to register the
device softc structure by hand at module load time. This seems
bogus, it should be called as a core part of the module load
process for character/block device drivers.
