82de09b2c0 Add pc98 specific code to adjust the firmware geometry when it differs
from the actual geometry.  This enables support of disks larger than
~120GB on pc98 boxes.  They make great little network appliances.
I've been using these changes for the past year or so on my network
storage pc98 box :-).

7067faff16 Remove sio(4) and related options from MI files to amd64, i386
and pc98 MD files. Remove nodevice and nooption lines specific
to sio(4) from ia64, powerpc and sparc64 NOTES. There were no
such lines for arm yet.
sio(4) is usable on less than half the platforms, not counting
a future mips platform. Its presence in MI files is therefore
increasingly becoming a burden.

a72b0bcd7f Simplify the pager support in DDB. Allowing different db commands to
install custom pager functions didn't actually happen in practice (they
all just used the simple pager and passed in a local quit pointer).  So,
just hardcode the simple pager as the only pager and make it set a global
db_pager_quit flag that db commands can check when the user hits 'q' (or a
suitable variant) at the pager prompt.  Also, now that it's easy to do so,
enable paging by default for all ddb commands.  Any command that wishes to
honor the quit flag can do so by checking db_pager_quit.  Note that the
pager can also be effectively disabled by setting $lines to 0.

Other fixes:
- 'show idt' on i386 and pc98 now actually checks the quit flag and
  terminates early.
- 'show intr' now actually checks the quit flag and terminates early.

11681ee0b5 Remove COMPAT_43 from GENERIC (and other kernel configs). For amd64 there's
an explicit comment that it's needed for the linuxolator. This is not the
case anymore. For all other architectures there was only a "KEEP THIS".
I'm (and other people too) running a COMPAT_43-less kernel since it's not
necessary anymore for the linuxolator. Roman is running such a kernel for a
for longer time. No problems so far. And I doubt other (newer than ia32
or alpha) architectures really depend on it.

This may result in a small performance increase for some workloads.

If the removal of COMPAT_43 results in a not working program, please
recompile it and all dependencies and try again before reporting a
problem.

The only place where COMPAT_43 is needed (as in: does not compile without
it) is in the (outdated/not usable since too old) svr4 code.

Note: this does not remove the COMPAT_43TTY option.

9e60ac43b5 Make the ISAPNP code optional and only enable it on i386 and pc98 (used
for CBUS-PNP cards there) by default, as there are no amd64 and sparc64
machines with ISA slots and which therefore could make use of this code
known to exist. For sparc64 this additionally allows to get rid of the
compat shims for in{b,w,l}()/out{b,w,l}() etc and the associated hacks.

038d1db25e Add the ability to subset the devices that UART pulls in. This allows
the arm to compile without all the extras that don't appear, at least
not in the flavors of ARM I deal with.  This helps us save about 100k.

know and I'll correct ASAP.

70daffddff - Add C-bus and ISA front-ends for le(4) so it can actually replace
lnc(4) on PC98 and i386. The ISA front-end supports the same non-PNP
  network cards as lnc(4) did and additionally a couple of PNP ones.
  Like lnc(4), the C-bus front-end of le(4) only supports C-NET(98)S
  and is untested due to lack of such hardware, but given that's it's
  based on the respective lnc(4) and not too different from the ISA
  front-end it should be highly likely to work.
- Remove the descriptions of le(4), which where converted from lnc(4),
  from sys/i386/conf/NOTES and sys/pc98/conf/NOTES as there's a common
  one in sys/conf/NOTES.

193a6144b9 Rewrite of puc(4). Significant changes are:
o  Properly use rman(9) to manage resources. This eliminates the
   need to puc-specific hacks to rman. It also allows devinfo(8)
   to be used to find out the specific assignment of resources to
   serial/parallel ports.
o  Compress the PCI device "database" by optimizing for the common
   case and to use a procedural interface to handle the exceptions.
   The procedural interface also generalizes the need to setup the
   hardware (program chipsets, program clock frequencies).
o  Eliminate the need for PUC_FASTINTR. Serdev devices are fast by
   default and non-serdev devices are handled by the bus.
o  Use the serdev I/F to collect interrupt status and to handle
   interrupts across ports in priority order.
o  Sync the PCI device configuration to include devices found in
   NetBSD and not yet merged to FreeBSD.
o  Add support for Quatech 2, 4 and 8 port UARTs.
o  Add support for a couple dozen Timedia serial cards as found
   in Linux.

deb16135f3 o Move ISA specific code from ppc.c to ppc_isa.c -- a bus front-
end for isa(4).
o  Add a seperate bus frontend for acpi(4) and allow ISA DMA for
   it when ISA is configured in the kernel. This allows acpi(4)
   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.

aaa33da2ed Don't allow userland to set hardware watch points on kernel memory at all.
Previously, we tried to allow this only for root.  However, we were calling
suser() on the *target* process rather than the current process.  This
means that if you can ptrace() a process running as root you can set a
hardware watch point in the kernel.  In practice I think you probably have
to be root in order to pass the p_candebug() checks in ptrace() to attach
to a process running as root anyway.  Rather than fix the suser(), I just
axed the entire idea, as I can't think of any good reason _at all_ for
userland to set hardware watch points for KVM.

4793b3db38 - 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.

cb0d490ebe 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.
