o It needs to have pcic_isa_intr intrrupt handler
o for pci interrupts, in the func interrupt handler it needs to check the isa
registers rather than the pci ones for card present.
o better commentary for some of the strangeness of the 6729 on pci
o fix some crunchy comments to better reflect reality.
With this I almost have the WL200 working, but an interrupt storm
after attach is causing problems for reasons unknown. This code
doesn't seem to break the normal clpd6729 case, and I'd like others
with 6729 cards to try to test it (there were some that were used for
external pccard slots in pci only systems).
to return a wired page.
o Use VM_ALLOC_WIRED within Alpha's pmap_growkernel(). Also, because
Alpha's pmap_growkernel() calls vm_page_alloc() from within a critical
section, specify VM_ALLOC_INTERRUPT instead of VM_ALLOC_SYSTEM. (Only
VM_ALLOC_INTERRUPT is implemented entirely with a spin mutex.)
o Assert that the page queues mutex is held in vm_page_wire()
on Alpha, just like the other platforms.
so it needs an explicit #include <machine/frame.h> to get 'struct
trapframe'. The fact that it needs this at this level is rather bogus
but it will not compile without it.

on the Itanium2 system I have when we use up *all* of the initial 256MB
direct mapped region before we are ready to dynamically expand it.
The machine that I have has 4 cpus and a very big hole in the middle.
This makes the bogus '(last_address - first_address) / PAGE_SIZE'
calculations especially dangerous and caused many millions of initial
PV/PTE's to be preallocated.
o Add preliminary support for Cirrus Logic CL-PD6729 using PCI
interrupts. To use it you you need to set hw.pcic.pd6729_intr_path
to 2. This is allow us to still default to ISA intrrupt path for
this part (which is found much more often in laptops using ISA IRQs).
But some PCI cards have this part on them and this should allow them
to be used. It is untested on PCI, but it seems to not break the ISA
case.
o Better sysctl descriptions (I hope).
machine will result in approximately a 4.2% loss of performance (buildworld)
and approximately a 5% reduction in power consumption (when idle). Add XXX
note on how to really make hlt work (send an IPI to wakeup HLTed cpus on
a thread-schedule event? Generate an interrupt somehow?).
in the .h file. Make it static __inline to make sure that it doesn't
wind up defined in any files.
Also, fix a typo that said null_do_attach instead of null_do_probe.

cv_wait() in order to allow threads to go to sleep and yeild the cpu

is no way to determine on which bus a busdma operation is performed.
While being there, clean up the iommu code a bit.
This should be a step in the direction of allow some of larger machines
to work; tests have shown that there still seem to be problems left.
