that add an instance of themselves. The npx(4) driver doesn't even check
the npx 'port' hint but hardcodes IO_NPX instead. The npx(4) driver also
will use isa IRQ 13 (on x86, 8 on pc98) by default if no 'irq' hint is
specified, so we don't need that hint either.

Whenever doing a copy-on-write check, first look in the list of
initially allocated blocks to see if it is there. If so, no further
check is needed. If not, fall through and do the full check. This
change eliminates one of two known deadlocks caused by snapshots.
Handling the second deadlock will be the subject of another check-in.
This change also reduces the cost of the copy-on-write check by
speeding up the verification of frequently checked blocks.

even when the underlying device has a larger sector size. Therefore,
the filesystem code should not (and with this patch does not) try to
use the underlying sector size when doing disk block address calculations.
This patch fixes problems in -current when using the swap-based
memory-disk device (mdconfig -a -t swap ...). This bugfix is not
relevant to -stable as -stable does not have the memory-disk device.

documentation already adequatedly existed in the description in most
cases. Where it did not, it was added. If no documentation existed
beforehand, then none was added. Some unused dummies for use in the
traversal functions were marked as __unused during the conversion.
Occasionally, local style fixes were applied to lines already being

in specific situations. The owner thread must be blocked, and the
borrower can not proceed back to user space with the borrowed KSE.
The borrower will return the KSE on the next context switch where
teh owner wants it back. This removes a lot of possible
race conditions and deadlocks. It is consceivable that the
borrower should inherit the priority of the owner too.
that's another discussion and would be simple to do.
Also, as part of this, the "preallocatd spare thread" is attached to the
thread doing a syscall rather than the KSE. This removes the need to lock
the scheduler when we want to access it, as it's now "at hand".
DDB now shows a lot mor info for threaded proceses though it may need
some optimisation to squeeze it all back into 80 chars again.

Upcalls are now "bound" threads, but "KSE Lending" now means that
other completing syscalls can be completed using that KSE before the upcall
finally makes it back to the UTS. (getting threads OUT OF THE KERNEL is
one of the highest priorities in the KSE system.) The upcall when it happens
will present all the completed syscalls to the KSE for selection.

The problem is that the code does a check for the granparent of
the Promise chip, if this is a bridge of the right type, we have
a TX4 on our hands, and need to handle that ones "issues".
Now the grandparent check cause subtle bugs in the newbus system,
mainly that pci_get_devid doesn't return an error value.
This patch works around the issue by using BUS_READ_IVAR() instead.
structure. This has been broken since 1998, but probably hasn't been
noticed because it takes a read/write of 64K blocks (32MB with 512 byte
blocks) to trigger using the 12 byte read/write CDB in scsi_read_write().

end of the string, leading to memory corruption and eventually SIGSEGV.
