cd.c:
Initialize channel info in CDIOCSETVOL ioctl.
Correct CDIOCSTOP and CDIOCEJCET ioctls to use scsi_stop_unit
instead of scsi_start_unit.
Add CDIOCALLOW and CDIOCPREVENT ioctls.
ch.h:
Return EBUSY instead of ENXIO if the device is already in use.
scsi_base.c:
Add scsi_stop_unit routine.
sd.c:
Add mising indirection through sc_link to sd_get_parms routine
when checking for media loaded.
st.c:
Return EBUSY instead of ENXIO if the device is already in use.
Clear the SDEV_WAITING flag in ststart if we do the wakeup call.
Cuddle { braces up where possible on if statements
Add missing splx(s) calls before some returns.
Remove extra semicolon that was keeping uha_init from returning
before the timeout occured. This should speed probing up quite
a bit!
0) FreeBSD additional include files additions
1) Rod's arpacom changes
2) Function type and return code cleanup, and all functions have correct
casting to the correct data types
3) Bugfix where driver would not function due to missing structure not
given a value.
4) General cleanup. (Theo did a lot already, I just did some more)
Removed com port comments, since we are about to depricate the driver.
Fix several plaes in LINT where people have been cutting and pasting using
xterms :-(
the device close routine. This works because the device close calls
the line discipline close (which only flushes the output buffers) and
the ttyclose() routine, which does little of nothing except screw with
the session and process group fields (which is what was causing all
the problems).

As reported on the -bugs list by some one, and confirmed by Julian:
> I increased AHA_RESET_TIMEOUT in aha1542.c from 1000 to 10000
> and now my 1542C is found everytime.
problem with some chipsets (UMC) remapping the 'hole' memory even when
you've got 16MB. People were led to believe that since there was only
16MB of memory in the machine, that they were okay wrt the ISA DMA
limit. This hack simply causes the extra memory to be ignored if it
appears around the 16MB limit.
* Removed pmap_is_wired
* added extra cli/sti protection in idle (swtch.s)
* slight code improvement in trap.c
* added lots of comments
* improved paging and other algorithms in VM system
Changed the output of the isa probe routine, that only devices, that
have an IO address and are smaller than 0x100 to be on the motherboard.
The seagate SCSI adapter is an example of a card, that doesn't have
an IO address and works only memory mapped.
Choose older MULTIPORT version, because lastest bde version
not worked.
Don't force HUPCL for bidirectional case.
From bde:
Use bit (1 << (16 + 4)) in schedsoftcom() to avoid clash with
non-serial h/w on IRQ4.
Allow FIFO_TRIGGER in config.
Clear com->mcr_image when clearing mcr for init of 4port. The
usual value MCR_IENABLE should have broken 4ports unless
something happened to clear it later.
Turn off interrupts as well as DTR after an error waiting for
carrier (bidir dialin case).
Drain fifo more carefully.
Don't hang up if debugging.
Rearrange siointr() -> siointr1() for multiport case for speed,
lower latency and clarity.
Use suser() to check perms.
Provide missing splx() after failed perms checks.
c_ispeed == 0 means c_ispeed = c_ospeed (POSIX).
Set parameters (except speed) for c_ospeed == 0 as well as
hanging up.
Better initialization for console (fifo stuff...).
Misc. cleanups.
Fix dead hang if modem power is off.
