actually used.
Remove "#ifdef __GNUC__" around some __dead* declarations. __dead* is
harmless if __GNUC__ is not defined.
Uniformize idempotency #ifdef.
2. Clean up code so it compiles -Wall (except for sccsid's and copyright).
This included fixing several printf formats that where not correct,
and changing the data types of a few things.
3. Implement new option -i that produces indented mtree output files.
4. Implement new option -n that turns off directory comments.
5. Only emit /set records if something has changed since the last one.
This code is mostly taken from the 1.1 port (which was in turn taken from
Dave Mills's kern.tar.Z example). A few significant differences:
1) ntp_gettime() is now a MIB variable rather than a system call. A few
fiddles are done in libc to make it behave the same.
2) mono_time does not participate in the PLL adjustments.
3) A new interface has been defined (in <machine/clock.h>) for doing
possibly machine-dependent things around the time of the clock update.
This is used in Pentium kernels to disable interrupts, set `time', and
reset the CPU cycle counter as quickly as possible to avoid jitter in
microtime(). Measurements show an apparent resolution of a bit more than
8.14usec, which is reasonable given system-call overhead.
is used instead of /usr/lib
io.c: add #include <machine/cpufunc.h> as instructed by David Greenman to
avoid inb/outb linking errors.
NOTE: I just discovered that if GNUC is not used the inline functions will not be expanded from the include file and real inb/outb functions would
be needed.
it onto a bunch of floppies in a semi-intelligent way.
Useful for things like: tar cf - . | gzip -9 | fdwrite -d /dev/rfd0.1720 -v
Where it will keep asking for floppies until tar is done.
/usr/libexec/getty doesn't properly interpret the '%d' escape. It tries
to use %P to get AM or PM, but instead all it gets is "P".

modload doesn't honor it's -p argument.
It also will destroy the input file when you don't specify an output
symbol file with -o.

when the drive had been left on a cylinder > 67 after kernel boot. The
most common case for this is booting a kernel that is located on
the inner cylinders of a floppy.
Also removed all occurences of spinwait(), replaced by DELAY.
Nuked a return line saying nothing, this might make Bruce happy 8^)

First round of floppy changes. Try making `fd' more robust.
New features:
. ioctl command for setting the drive type (density etc.); restricted
to the super-user
. ioctl for getting/seting `drive options'; currently only option
is FDOPT_NORETRY: inhibit the usual retries; used when verifying
a newly formatted track
Fixes:
. function prototypes
. made all internal functions `static'
. cleaned up & corrected .h files
. restructured, to make the chaotic function sequence more rational
. compiled with -Wall, and cleared all warnings
. introduced a mirror for the (write-only) `digital output register',
to avoid the current kludge
. device probing completed by seeking/recalibrating, and looking
for track 0 being found
. holding the controller down in reset state while it is idle (and
thus saving allot of headaches)
. make requests fail that are not a multiple of the (physical)
sector size
. removed the fixed physical sector size (512 bytes), allowing for any
size the controller could handle (128/256/512/1024 bytes)
. replaced some silly messages
. fixed the TRACE* macro usage, debugging reports should be complete
now again (debugging output is HUGE! though)
. removed fd_timeout for SEEK command; seeks are always reported by
the controller to succeed, since the `success' only refers to the
controller's idea of success - there is no hardware line to tell about
the seek end (other than the `track 0' line)
. catch SENSEI's that report about a `terminated due to READY changed'
status - could happen after a controller reset
. converted ``hz / <something>'' divide operations to divisors that are
powers of two, so gcc can optimize them into shifts
. write/format operations are checked against a write-protected medium
now *prior* starting the operation
. error reports of `invalid command' and `wrong cylinder' will cause
shortcuts in the retrier() now
. fixed a bug in the retrier() causing bogus block numbers to be reported
. fdformat() does care for errors now
Known Bugs:
. no attempts have been made (yet) to improve the performance
. sometimes, bogus ``seek/recalib failed'' messages are logged; this
is still a bug in the driver, but it's not harmful since it's
usually caught by the retrier()
