3de213cc00 Add a new 'why' argument to kdb_enter(), and a set of constants to use
for that argument.  This will allow DDB to detect the broad category of
reason why the debugger has been entered, which it can use for the
purposes of deciding which DDB script to run.

Assign approximate why values to all current consumers of the
kdb_enter() interface.

c848e0de55 Mfi386 revision 1.239 of src/sys/i386/isa/clock.c. Seemingly some
pc98 motherboards do not provide us with the correct day of week
either. Ignore the day of week when setting the clock here too.

041b706b2f Despite several examples in the kernel, the third argument of
sysctl_handle_int is not sizeof the int type you want to export.
The type must always be an int or an unsigned int.

Remove the instances where a sizeof(variable) is passed to stop
people accidently cut and pasting these examples.

In a few places this was sysctl_handle_int was being used on 64 bit
types, which would truncate the value to be exported.  In these
cases use sysctl_handle_quad to export them and change the format
to Q so that sysctl(1) can still print them.

cec54a8d96 Oops, pc98 is independent of i386 for clock.c and machdep.c but not
for clock.h, so changing th i386 clock.h broke it.  MFi386 (not tested):

Cleaned up declaration and initialization of clock_lock.  It is only
used by clock code, so don't export it to the world for machdep.c to
initialize.  There is a minor problem initializing it before it is
used, since although clock initialization is split up so that parts
of it can be done early, the first part was never done early enough
to actually work.  Split it up a bit more and do the first part as
late as possible to document the necessary order.  The functions that
implement the split are still bogusly exported.

Cleaned up initialization of the i8254 clock hardware using the new
split.  Actually initialize it early enough, and don't work around it
not being initialized in DELAY() when DELAY() is called early for
initialization of some console drivers.

This unfortunately moves a little more code before the early debugger
breakpoint so that it is harder to debug.  The ordering of console and
related initialization is delicate because we want to do as little as
possible before the breakpoint, but must initialize a console.

b69f71eb29 Second part of a little cleanup in the calendar/timezone/RTC handling.
Split subr_clock.c in two parts (by repo-copy):
   subr_clock.c contains generic RTC and calendaric stuff. etc.
   subr_rtc.c contains the newbus'ified RTC interface.

Centralize the machdep.{adjkerntz,disable_rtc_set,wall_cmos_clock}
sysctls and associated variables into subr_clock.c.  They are
not machine dependent and we have generic code that relies on being
present so they are not even optional.

9fddcc6661 Fix our ioctl(2) implementation when the argument is "int". New
ioctls passing integer arguments should use the _IOWINT() macro.
This fixes a lot of ioctl's not working on sparc64, most notable
being keyboard/syscons ioctls.

Full ABI compatibility is provided, with the bonus of fixing the
handling of old ioctls on sparc64.

o  Add a seperate bus frontend for acpi(4) and allow ISA DMA for

   attachments in non-ISA configurations, as is possible for ia64.
o  Add a seperate bus frontend for pci(4) and detect known single
   port parallel cards.
o  Merge PC98 specific changes under pc98/cbus into the MI driver.
   The changes are minor enough for conditional compilation and
   in this form invites better abstraction.
o  Have ppc(4) usabled on all platforms, now that ISA specifics
   are untangled enough.

57fb5e6097 - Use bus_setup_intr() and bus_teardown_intr() to register device driver
interrupt handlers rather than BUS_SETUP_INTR() and BUS_TEARDOWN_INTR().
  Uses of the BUS_*() versions in the implementation of foo_intr methods
  in bus drivers were not changed.  Mostly this just means that some
  drivers might start printing diagnostic messages like [FAST] when
  appropriate as well as honoring mpsafenet=0.
- Fix two more of the ppbus drivers' identify routines to function
  correctly in the mythical case of a machine with more than one ppbus.

b439e431bf Tweak how the MD code calls the fooclock() methods some. Instead of
passing a pointer to an opaque clockframe structure and requiring the
MD code to supply CLKF_FOO() macros to extract needed values out of the
opaque structure, just pass the needed values directly.  In practice this
means passing the pair (usermode, pc) to hardclock() and profclock() and
passing the boolean (usermode) to hardclock_cpu() and hardclock_process().
Other details:
- Axe clockframe and CLKF_FOO() macros on all architectures.  Basically,
  all the archs were taking a trapframe and converting it into a clockframe
  one way or another.  Now they can just extract the PC and usermode values
  directly out of the trapframe and pass it to fooclock().
- Renamed hardclock_process() to hardclock_cpu() as the latter is more
  accurate.
- On Alpha, we now run profclock() at hz (profhz == hz) rather than at
  the slower stathz.
- On Alpha, for the TurboLaser machines that don't have an 8254
  timecounter, call hardclock() directly.  This removes an extra
  conditional check from every clock interrupt on Alpha on the BSP.
  There is probably room for even further pruning here by changing Alpha
  to use the simplified timecounter we use on x86 with the lapic timer
  since we don't get interrupts from the 8254 on Alpha anyway.
- On x86, clkintr() shouldn't ever be called now unless using_lapic_timer
  is false, so add a KASSERT() to that affect and remove a condition
  to slightly optimize the non-lapic case.
- Change prototypeof  arm_handler_execute() so that it's first arg is a
  trapframe pointer rather than a void pointer for clarity.
- Use KCOUNT macro in profclock() to lookup the kernel profiling bucket.

db015a9153 Fixup some more fallout from the lapic/i8254 changes:
- Make sure timer0_max_count is set to a correct value in the lapic case.
- Revert i8254_restore() to explicitly reprogram timer 0 rather than
  calling set_timer_freq() to do it.  set_timer_freq() only reprograms
  the counter if the max count changes which it never does on resume.  This
  unbreaks suspend/resume for several people.
