multiple times, others do. The last strategy, which was to assume
that already routed interrupts were good and just return them doesn't
work for some laptops. So, instead, we have a new strategy: we notice
that we have an interrupt that's already routed. We go ahead and try
to route it, none the less. We will assume that it is correctly
routed, even if the route fails. We still assume that other failures
in the bios32 call are because the interrupt is NOT routed.
Note: some laptops do not support the bios32 interface to PCI BIOS and
we need to call it via the INT 2A interface. That is another windmill
to till at later.

The workaround is to rewrite the EEPROM to disable Dynamic Standby Mode.
Once the EEPROM is rewritten, the system needs to be rebooted in order

[*] Looks like my pc98 machine has some interrupt source on IRQ 15
that gave about 30 interrupts per second, which masked this problem on
my PC-9821Nr15.
Briefly, the significant changes include:
* Way better resource management in pccbb, pccard and cardbus.
* pccard hot-removal now appears to work.
* support pre-fetchable memory in cardbus.
* update cardbus to support new pci bus interface functions.
* Fix CIS reading to no longer use rman_get_virtual().
What's not there, but in the works:
* pccard needs to do interrupt properly and not read the ISR on single
function cards.
* real resource management for pccard
* a complete implementation of CIS parsing
* need to look into how to correctly use mutex in pccbb

unfortunatly it does this all (the sizing, the buffer copying, and the
expiration GC) with no spl protection whatsoever. it was possible for
the dynamic rule(s) to be ripped out from under the request before it

to supply the number of bytes to be bcopy()'d to move an entry. If
d_ino == 0 however, DIRSIZ() is not guaranteed to return a sensible
length, so ufs_direnter could end up corrupting a directory during
compaction. In practice I believe this can only happen after fsck_ffs
has fixed a previously-corrupted directory.
We now deal with any mid-block unused entries specially to avoid
using DIRSIZ() or bcopy() on such entries. We also ensure that the
variables 'dsize' and 'spacefree' contain meaningful values at all
times. Add a few comments to describe better this intricate piece
of code.
The special handling of mid-block unused entries makes the dirhash-
specific bugfix in the previous revision (1.53) now uncecessary,
so this change removes it.

Basically, this fixes booting kernels compiled with MUTEX_DEBUG. What used

called mtx_init() on several mutex locks, notably Giant and some others.
This is a problem for MUTEX_DEBUG because it enables mtx_validate() which
calls kernacc(), some of which in turn requires Giant.
Fix by calling kernacc() from mtx_validate() only if (!cold).

This may fix the hangs some people are seeing on warmboot. It appears
that some machines will reset the cardbus bridge on boot, while others
don't. So we turn off the card, and ack the interrupts (which likely
is a nop in the shutdown case since we're still fielding interrupts).
This should turn off the interrupts.
