We assert no locks held during the cv wait, meaning we should

Don't force 16-byte alignment at run-time. Do it at compile-time.
This saves us the pointer fiddling by the setjmp functions and
reduces complexity. While here, increase the jmp_buf by 16 bytes
to an even 512 bytes. Coincidentally, due to the way alignment
was handled prior to this change, the jmp_buf has not changed in
size, but only in how the space is used. Prior to this change
the 16 bytes were reserved for enforcing alignment; now they are
reserved by us for future extensions.
Therefore, this ABI breaker is relatively save: the failure is
always an alignment trap.

This avoids the cost of the entry point in the common case, but
requires policies interested in the userret event to set the flag
(protected by the scheduler lock) if they do want the event. Since
all the policies that we're working with which use mac_thread_userret()
use the entry point only selectively to perform operations deferred
for locking reasons, this maintains the desired semantics.

take advantage of the fact that the vm object's list of pages is

1. At least some Netra t1 models have PCI buses with no associated
interrupt map, but obviously expect the PCI swizzle to be done with
the interrupt number from the higher level as intpin. In this case,
the mapping also needs to continue at parent bus nodes.
To handle that, add a quirk table based on the "name" property of
the root node to avoid breaking other boxen. This property is now
retrieved and printed at boot.
2. On SPARCengine Ultra AX machines, interrupt numbers are not mapped
at all, and full interrupt numbers (not just INOs) are given in
the interrupt properties. This is more or less cosmetical; the
PCI interrupt numbers would be wrong, but the psycho resource
allocation method would pass the right numbers on anyway.

hack, and replaces it with a softc flag that is used to record when
the handling of a no-resource condition was deferred due to running
out of DEVICE_POLLING cycles. This was tested on -stable, but the
code is essentially the same as in -current. It should only affect
the case where DEVICE_POLLING is defined.
The details of the mechanism behind the crashes are still uncertain
but the most likely cause seems to be some kind of hardware confusion
when the no-resource recovery code is accidentally invoked while
the receiver is still active. This could have happened if the
hardware left the 0x4000 bit of the RFA status word set. The comments
in the commit log for revision 1.142 stating that the driver could
clash with the hardware writing to this status word were not correct.
