2079f86890 On-board devices on psycho machines seem to have the `interrupt' property 
in the parent bus format (i.e. an INO) rather than being represented as
an PCI interrupt line. Provide a hack to work around this in pci_attach_hook().

34270e85bd Use probeget() in pci_config_read() for the psycho, to avoid bus

7e8f67ad97 No need to fetch the psycho's own registers as thet are already passed 
down from the parent bus.  Also account for the difference in `reg'
properties in psycho vs sabre chips.

f56554a578 If there is no "interrupt-map" property on the ebus node, assume the 
child "interrupt" properties are already in a format suitable for

e5cd515b89 Upgrate interrupt handling: 
1) use interrupt vectors for specific zs chips rather than polling
	   all of them.

	2) use softintr_schedule() and schedule it for a particular device
	   rather than poll all devices.

406e0f779f Add a `device class' interrupt level argument (from machine/intr.h) 
to bus_interrupt_establish().

It's currently only used in sparc64/dev/psycho.c to assign a CPU interrupt
level to devices in PCI slots.

585f7645bf iommu_dvmamap_load*(), pass an alignment constraint, as well as 
EX_BOUNDZERO, to extent_alloc().  this fixes problems with it
(extent_alloc()) returning incorrect values, when the start of
the extent is not aligned as strongly as the requested area..

raw access to ide disks now works.

889c658b5b Change the kernel mmap interface so that the offset to map is an 
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes.  Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".

Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.
