structure and 'aux', right before ca_attach is called for the
newly-attached device. This allows the alpha port to do root device
autodetection without modifying every bus and device driver which could
be in the 'boot path.' In the long run, it may make sense to make
this machine-independent.
an extended header is present i.e. don't assume an extended header as
however unlikely there could be a podule that doesn't have one.
Calculate an absolute address for the podule's interrupt mask rather
than leaving it relative to the base address of the podule.
If the interrupt status pointers are not present or are zero then
used the default bits as specified in the podule specification to
determine if the podule is interrupting.
chained podule interrupt handlers.
Fill out the ih_maskaddr and ih_maskbits fields in the interrupt handler
structure so that interrupt dispatcher knows where to look to determine
if the handler should be called.
General code tidy up and source code formatting.

back on timer 1 interrupts if none is specified.
Only set up timer 1 is the driver is using timer 1 interrupts.
Don't claim the interrupt but allow them to be passed on to other
handlers.
Fixed the handling of IPL_NONE.
Debugged support for interrupt chaining.
Fill out the intrnames array with the name of the interrupt handler
currently at the head of the chain.
Guarded several sanity checks with #ifdef DIAGNOSTIC.
Added interrupt chaining.
Removed some dead debugging code.
Guarded several sanity checks with #ifdef DIAGNOSTIC
Make sure interrupts are disable while updating the IOMD interrupt
masks.
Removed several old debugging functions that are no longer needed.
Block interrupts while updating the soft interrupt masks.
Fixed softclock interrupts and added IRQ_SOFTPLIP to the SPL_SOFT mask.
Rename the currently unused irq handler structure fields for podule
interrupts so they make more sense.
Define IPL_NONE as a positive value instead of -1 and increase the
number of IPL levels.
from from the corresponding `ic_*' and `dc_*' values. This is not perfect,
but it makes SS4s and SS5s run until we have proper per-cpu cache handling.
Use the `cache-physical?' property to determine the value of `vactype'
on sun4m's. If absent, set vactype to VAC_WRITETHROUGH (XXX) else VAC_NONE.
Print simpler sun4m CPU identifier on attach.

using HASHFRACTION directly. in time-critical calculations, if HASHFRACTION
is a power of two, check that p->hashfraction == HASHFRACTION and if so do
the calculation with the compiled-in value so that the compiler can optimize
out (potentially) expensive divisions. if p->hashfraction != HASHFRACTION,
actually do the division. This has the result that on machines with slow
division, the division can be optimized out of the common case, but that
if HASHFRACTION changes from the compiled-in value (for whatever reason),
profiling will still work. Changes suggested by Chris Torek.
(1) right now GENERIC can boot via NFS, and
(2) in the long run, GENERIC should autodetect network booting
and pick the correct root device.
Because of (1), GENERIC_NFS is no longer _needed_ in the short term.
Because of (2), GENERIC_NFS is not _wanted_ in the long term.
and whacking a bit here and there where appropriate. Does not yet do
automatic root device detection, but that's much easier to add now.
RB_ASKNAME now supports specification of network devices, for diskless
booting. Also, RB_ASKNAME is now supported on _all_ kernels.
