- Mark interrupt handler MPSAFE (IFF_NEEDGIANT was already clear).
- Lock the driver lock in driver entry points such as the interrupt
handler, if_start, and if_init rather than locking the driver mutex
in the various work functions called by the binary blob. The spin lock
used by the binary block can probably be stubbed out now.

the IRQ set by the BIOS in existing devices to actually get the correct
bus number of the child PCI bus. I was not reading the bus number from
the bridge device correctly. The __BUS_ACCESSOR() macros (from which
pcib_get_bus() is built) assume that the passed in argument is a child
device. However, at the time I'm reading the bus there is no child
device yet, so I was passing in the pcib device as the child device.
The parent of the pcib device probably returned an error in the case of
a host bridge, thus resulting in random stack garbage for the bus number.
For PCI-PCI bridges, the bus number being used was actually the subvendor
of the PCI-PCI bridge device itself.

via the DEFAULTS kernel configs. This allows folks to turn it that option
off in the kernel configs if desired without having to hack the source.
This is especially useful since PUC_FASTINTR hangs the kernel boot on my
ultra60 which has two uart(4) devices hung off of a puc(4) device.
I did not enable PUC_FASTINTR by default on powerpc since powerpc does not
currently allow sharing of INTR_FAST with non-INTR_FAST like the other
archs.

interrupt handler (we actually borrow the apic one that just does an
immediate iret) to handle any spurious interrupts triggered by either chip.
This should fix some folks that were getting a Trap 30 during bootup of
certain SMP AMD systems. This might get pushed into the 6.0 branch as an
errata. For now a suitable workaround is to add 'device atpic' to your
kernel config.

- TX/RX decriptor length should be multiple of 128. There is no

- don't create/destroy DMA maps in TX/RX handlers. Use pre-allocated

operations(resource mananger overhead), this change should boost
performance on sparc64. I could get > 2x speedup on Ultra60.
- TX/RX descriptors could be aligned on 128 boundary. Aligning them

for a Windows ISR is 'BOOLEAN isrfunc(KINTERRUPT *, void *)' meaning
the ISR get a pointer to the interrupt object and a context pointer,
and returns TRUE if the ISR determines the interrupt was really generated
by the associated device, or FALSE if not.
I had mistakenly used 'void isrfunc(void *)' instead. It happens the
only thing this affects is the internal ndis_intr() ISR in subr_ndis.c,
but it should be fixed just in case we ever need to register a real
Windows ISR vi IoConnectInterrupt().
For NDIS miniports that provide a MiniportISR() method, the 'is_our_intr'
value returned by the method serves as the return value from ndis_isr(),
and 'call_isr' is used to decide whether or not to schedule the interrupt
handler via DPC. For drivers that only supply MiniportEnableInterrupt()
and MiniportDisableInterrupt() methods, call_isr is always TRUE and
is_our_intr is always FALSE.
In the end, there should be no functional changes, except that now
ntoskrnl_intr() can terminate early once it finds the ISR that wants
to service the interrupt.
When all file systems have a time stamp of zero, which is the case
for example when the root file system is on a read-only medium, we
ended up not calling inittodr() at all. A potential uncleanliness
existed as well. If multiple file systems had a non-zero time stamp,
we would call inittodr() multiple times. While this should not be
harmful, it's definitely not ideal.
Fix both issues by iterating over the mounted file systems to find
the largest time stamp and call inittodr() exactly once with that
time stamp. This could of course be a zero time stamp if none of the
mounted file systems have a non-zero time stamp. In that case the
annoying errors mentioned in the commit log for revision 1.186 still
haven't been avoided. The bottom line is that inittodr() should not
complain when it gets a time base of zero. At the time of this
commit only alpha seems to have that problem.

in vfs_domount(), so we need to do the parsing for these particular
mount flags earlier on. The new flags parsed are:
async, force, multilabel, noasync, noatime, noclusterr, noclusterw,
noexec, nosuid, nosymfollow, snapshot, suiddir, sync, union.
Existing code which uses mount() to mount UFS filesystems is not
affected, but new code which uses nmount() to mount UFS filesystems
should behave better.
