Updates:
- don't bypass SYNCHRONIZE_CACHE command
- return SCSI_MLQUEUE_HOST_BUSY when no free request slots
- move scsi_remove_host() to the begin of hpt_remove(), or it will
not work after resources being released.

This is a hold over from the end device/expander conversion. Apparently
the rphy list pointer is never initialised, so list_del() on the
uninitialised pointer can panic the system

The RQ_SCSI_* flags are a vestiage of a long past history. The EH code
still sets them but we never make use of that information. The other
users is pluto.c which never had a chance to work but needs to be kept
compiling to keep Davem happy, so copy over the definition there.
We could probably get rid of RQ_ACTIVE/RQ_INACTIVE aswell with some
work, there's only two more or less bogus looking uses in ubd and scsi.

The driver uses msleep_interruptible() in the code path responsible
for resetting the card's ports via the lsiutil command. If a
<ctrl-c> is received during the reset it can leave a port in such
a state that the only way to regain its use is to reboot the system.
Changing from msleep_interruptible() to msleep() corrects the problem.

While doing board reset testing I was able to put the system in
an infinite request/response loop between the scsi layer and
mptscsih_qcmd() by aborting the reset. This patch installs
a "SETUP RESET" handler which calls fc_remote_port_delete()
for all registered rports. This blocks the target which
prevents the loop. Additionally, should the reset fail to
complete, the transport will now terminate i/o to the target.

The fibre channel firmware provides a timer which is similar in purpose
to the fibre channel transport's device loss timer. The effect of this
timer is to extend the total time that a target will be missing beyond
the value associated with the transport's timer. This patch changes
the firmware timer to a default of one second which significantly reduces
the lag between when a target goes missing and the notification of the
fibre channel transport.

Looking at the reiser4 crash, I found a leak in debugfs. In
debugfs_mknod(), we create the inode before checking if the dentry
already has one attached. We don't free it if that is the case.
These bugs happen quite often, I'm starting to think we should disallow
such coding in CodingStyle.

There's a race between shutting down one io scheduler and firing up the
next, in which a new io could enter and cause the io scheduler to be
invoked with bad or NULL data.
To fix this, we need to maintain the queue lock for a bit longer.
Unfortunately we cannot do that, since the elevator init requires to be
run without the lock held. This isn't easily fixable, without also
changing the mempool API. So split the initialization into two parts,
and alloc-init operation and an attach operation. Then we can
preallocate the io scheduler and related structures, and run the attach
inside the lock after we detach the old one.
This patch has survived 30 minutes of 1 second io scheduler switching
with a very busy io load.

This patch fixes a kernel panic during boot that occurs on NVIDIA platforms
that have HPET enabled.
When HPET is enabled, the standard timer IRQ is routed to IOAPIC pin 2 and is
advertised as such in the ACPI APIC table - but an earlier workaround in the
kernel was ignoring this override. The fix is to honor timer IRQ overrides
from ACPI when HPET is detected on an NVIDIA platform.

Trimming the head of an skb by calling skb_pull can cause the packet
to become unaligned if the length pulled is odd. Since the length is
entirely arbitrary for a FIN packet carrying data, this is actually
quite common.
Unaligned data is not the end of the world, but we should avoid it if
it's easily done. In this case it is trivial. Since we're discarding
all of the head data it doesn't matter whether we move skb->data forward
or back.
However, it is still possible to have unaligned skb->data in general.
So network drivers should be prepared to handle it instead of crashing.
This patch also adds an unlikely marking on len < headlen since partial
ACKs on head data are extremely rare in the wild. As the return value
of __pskb_trim_head is no longer ever NULL that has been removed.
