eb51e37703 Remove some unnecessary #includes.
Restore the simple leap year calculation as a macro and document it so
that it doesn't become complicated again.  The simple version works
for all leap years covered by 32-bit time_t's.  The complicated version
doesn't work for all leap years covered by 64-bit time_t's since among
other reasons, the solar system is not stable for long enough.

Fix declarations.

3f31c649d1 Redo Kernel NTP PLL support, kernel side.
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.

6b7bd95b6d Fixed the problem where the floppy has incorrectly failed probing
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^)

3a2f7427fe Updated driver to the 1.1.5 version:
date: 1994/05/22 12:35:38;  author: joerg;  state: Exp;  lines: +6 -6
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()

5b7ffe398f Digicom Systems Inc, makes "softmodems". What this means is simply that
you download the microcode to the DSP everytime you power on your system.
They provide a dos-program to do so, but no other support.  This commit adds
code to the sio-driver, which implement an ioctl, which will down-load the
micro-code.

To get this functionality, you must define DSI_SOFT_MODEM.

The program to actually employ the ioctl is not included, but the entire
source looks like this:

        #include <sys/ioctl.h>
        #include <stdio.h>

        main()
        {
                unsigned char buffer[100000];
                int i;

                read(0,buffer,100000);
                if((i = ioctl(1,TIOCDSIMICROCODE,buffer)) < 0)
                    perror("ioctl");
                return i;
        }

And you use it like this:
	smload < data144b.dsi > /dev/ttyid3

You need to copy the *.DSI files from the dos-media provide with your modem.
You can see what is downloaded by issuing the ATI3 command to the modem.
DSI's scheme for what code you can run on your modem isn't violated by this.

8a129caed5 1) Changed ddb into a option rather than a pseudo-device (use options DDB
in your kernel config now).
2) Added ps ddb function from 1.1.5. Cleaned it up a bit and moved into its
   own file.
3) Added \r handing in db_printf.
4) Added missing memory usage stats to statclock().
5) Added dummy function to pseudo_set so it will be emitted if there
   are no other pseudo declarations.

3e0a35fee4 Updated to final 1.1.5 version (revision 1.56).
Merged changes from 2.0 version (revisions 1.46-1.50) by hand.

Finished conversion to clists: removed flush of tty output buffer
in comflush() (most writes were truncated to 256 bytes) and restored
bypass of ttyinput() in siopoll().

Finished conversion to 2.0 types - more void *'s, less caddr_t's,
less casts, no Dev_t's.

Only these things are seriously broken now compared with 1.1.5:
waiting for output complete is impossible so ttywait() can deadlock;
sioclose() isn't called enough so sioopen() sometimes returns EBUSY
unnecessarily; input flow control is not implemented.

Main change:
	Removed the timeout_func_t casts from timeout calls and
	correctly defined the timeout routines to conform to
	the new format.
lpt.c doesn't have this change.

f23b4c91c4 Fix up some sloppy coding practices:
- Delete redundant declarations.
- Add -Wredundant-declarations to Makefile.i386 so they don't come back.
- Delete sloppy COMMON-style declarations of uninitialized data in
  header files.
- Add a few prototypes.
- Clean up warnings resulting from the above.

NB: ioconf.c will still generate a redundant-declaration warning, which
is unavoidable unless somebody volunteers to make `config' smarter.

8912c0ed61 Bruce Evans' dynamic interrupt support.
/usr/src/sys/i386/isa/clock.c:
	o Garrett's statclock changes.
	o Wire xxxintr, not Vclk.
	o Wire using register_intr(), not setidt().

/usr/src/sys/i386/isa/icu.s:
	o Garrett's statclock changes.
	o Removed unused variable high_imask.
	o Fake int 8 for rtc as well as int 0 for clk.  Required for kernel
	  profiling with statclock, harmless otherwise.

/usr/src/sys/i386/isa/isa.c:
	o Allow isdp->id_irq and other things in *isdp to be changed by
	  probes.  Changing interrupts later requires direct calls to
	  register_intr() and unregister_intr() and more care.
	  ALLOW_CONFLICT_* is brought over from 1.1.5, except
	  ALLOW_CONFLICT_IRQ is not supported.  IRQ conflict checking is
	  delayed until after probing so that drivers can change the IRQ
	  to a free one; real conflicts require more cooperation between
	  drivers to handle.
	o Too many details to list.
	o This file requires splitting and a lot more work.

/usr/src/sys/i386/isa/isa_device.h:
	o Declare more things more completely.

/usr/src/sys/i386/isa/sio.c:
	o Prepare to register interrupt handlers as fast.

/usr/src/sys/i386/isa/vector.s:
	o Generate entry code for 16 fast interrupt handlers and 16 normal
	  interrupt handlers.  Changed some constants to variables:
	  # $unit is now intr_unit[intr].  Type is int.  Someday it should
	    be a cookie suitable for the handler (e.g., a struct com_s for
	    sio).
	  # $handler is now intr_handler[intr].
	  # intrcnt_actv[id_num] is now *intr_countp[intr].  The indirection
	    is required to get a contiguous range of counters for vmstat
	    and so that the drivers depend more in the driver than on the
	    interrupt number (drivers could take turns using an interrupt
	    and the counts would remain correct).  There is a separate
	    counter for each device and for each stray interrupt.  In
	    1.1.5, stray interrupt 7 clobbers the count for device 7 or
	    something worse if there is no device 7 :-(.
	  # mask is now intr_mask[intr] (was already indirect).
	 o Entry points are now _XintrI and _XfastintrI (I = intr = 0-15),
	   not _VdevU (U = unit).
	 o Removed BUILD_VECTORS stuff.  There's a trace of it left for
	   the string table for vmstat but config now generates the
	   string in one piece because nothing more is required.
	 o Removed old handling of stray interrupts and older comments
	   about it.
