d29883b254 Widen the enable/disable helper function's argument in line with the
ithread_create() changes etc.  This should be mostly a NOP.

fdead95125 Prefer new location of pci include files (which have only been in the
tree for two or more years now), except in a few places where there's
code to be compatible with older versions of FreeBSD.

7db6a715d6 Cleanup <machine/cpu.h> by moving MD prototypes to <machine/md_var.h>
like we have on other platforms. Move savectx() to <machine/pcb.h>.
A lot of files got these MD prototypes through the indirect inclusion
of <machine/cpu.h> and now need to include <machine/md_var.h>. The
number of which is unexpectedly large...

osf1_misc.c especially is tricky because szsigcode is redefined in
one of the osf1 header files. Reordering of the include files was
needed.

linprocfs.c now needs an explicit extern declaration.

72688ad7fe Change the console interface to pass a "struct consdev *" instead of a
dev_t to the method functions.

The dev_t can still be found at struct consdev *->cn_dev.

Add a void *cn_arg element to struct consdev which the drivers can use
for retrieving their softc.

3bf8ca0614 Initialise the AS4100 console at the same time as most of the other
platform types instead of deferring it until the mcpcia devices are
probed. This allows the use of e.g. kgdb before the busses are probed.

2463f40fc3 Introduce a standard name for the lock protecting an interrupt controller
and it's associated state variables: icu_lock with the name "icu".  This
renames the imen_mtx for x86 SMP, but also uses the lock to protect
access to the 8259 PIC on x86 UP.  This also adds an appropriate lock to
the various Alpha chipsets which fixes problems with Alpha SMP machines
dropping interrupts with an SMP kernel.

7e987d1dff Doug found that doing a W1C on MCPCIA_INT_REQ just around the time you
clear MCPCIA_INT_MASK0 helps things substantially. So, why not indeed?

Rearrange irq and cookie calculation to use shifts/masks instead
of division. Fix things to correctly remember the intpin for that
one in a million non-INTA PCI device.

b31e6b9052 Doug noticed that the bit values for _MCPCIA_INT_ACK0/_MCPCIA_INT_ACK1
made no sense in the context of wrapping them within the _SYBRIDGE macro-
or anything like it- so we concluded that this must have been a typo
in the docs.  This also doesn't use the same bridge offset as anything
else.

Add some defines for the INT_CTL register.

5c912a2091 Clean this is up a bit for multiple MIDs... We can figure out which MID
for an interrupt to enable/disable from the vector (and GID too, if we
had multiple GIDs)- so, stupidly for now, search for the right mcpcia's
softc so we have the right base address for the bridge CSR to apply
IRQ bit-twiddle's to. Alas- this doesn't yet allow us to run, but it's
the right direction.

71938e9fcd - Heavyweight interrupt threads on the alpha for device I/O interrupts.
- Make softinterrupts (SWI's) almost completely MI, and divorce them
  completely from the x86 hardware interrupt code.
  - The ihandlers array is now gone.  Instead, there is a MI shandlers array
    that just contains SWI handlers.
  - Most of the former machine/ipl.h files have moved to a new sys/ipl.h.
- Stub out all the spl*() functions on all architectures.

dd8b44b395 * Completely rewrite the alpha busspace to hide the implementation from
the drivers.
* Remove legacy inx/outx support from chipset and replace with macros
  which call busspace.
* Rework pci config accesses to route through the pcib device instead of
  calling a MD function directly.

With these changes it is possible to cleanly support machines which have
more than one independantly numbered PCI busses. As a bonus, the new
busspace implementation should be measurably faster than the old one.

6ebbbb92bd Handle (for now) trivial one level bridge case so we can get the

448fe174f0 Coordinate with change to mcpcia_pci.c- major primary busses on each
hose are 16 PCI instances apart. This allows us to recognize secondary
PCI busses (at least to a first level) until the pci infrastructure is
fixed.

Turn on support for secondary cycles, too.  Redo debug printouts.

0c19638e64 Change references/comments about 'secondary' to reflect that while we'd
like to see the true SRM bus number be passed to us, instead, we get FreeBSD's
PCI bus instance number (Brzzt! Wrong Answer!).

Also, once we've seen the MCPCIA that has the EISA bus on it, call
dec_kn300_cons_init just before configuring devices on this bus.
