The BLIST_REPORTLUN2 blacklist item has exactly the behavior that
the MYLEX DACARMRB (and SGI TP9100, which is really a 2Gb upgrade
to the DACARMRB) need.

These devices use a PQ of 1 instead of 3 for unconfigured luns,
which means that every RAID has 32 luns, many or most of which
are just phantoms.

However, it does support Report Luns, and it returns the correct
data.

The object of this infrastructure is to give HBAs early warning that
error handling is about to happen and also provide them with the
opportunity to do something about it.

It introduces the extra template callback:

eh_timed_out()

which scsi_times_out() will call if it is populated to notify the LLD
that an outstanding command took a timeout.

There are three possible returns:

EH_HANDLED:	I've fixed the problem, please complete the command for me
(as soon as the timer fires, scsi_done will do nothing, so the timer
itself will call a special version of scsi_done that doesn't check the
timer).

EH_NOT_HANDLED:	Invoke error recovery as normal

EH_RESET_TIMER:	The command will complete, reset the timer to its
original value and start it ticking again.

I've been going through Mark's changes with a fine toothcomb and this merges
most of them. Its tested on 64bit SMP hardware and seems to be fine. There
are a couple of Mark's changes I've left out for now but there isnt really
an easy way to break down the changes further.

This fixes a whole host of problems including random hangs under high load

Since arg is a user pointer, so are uioc_mimd and uiocp, and hence umc is a
user pointer.  Thus reading umc->xferaddr requires dereferencing a user
pointer, which isn't safe.

This patch fixes orphaned expectations, which can occur when helpers create
expectations for unconfirmed conntracks and the packet is dropped before
the conntrack is confirmed.

Tracked down by Raivis Bucis <raivis@mt.lv>

This patch fixes an oops while listing /proc/net/ip_conntrack.

When a helper sets up expectations based on the first packet (tftp),
NAT can still change the packet and cause conntrack to look for a new helper
based on the new tuple. When no helper is found, expectant->helper will be
NULL, which leads to an oops in print_expect().
 
Only assign a new helper in ip_conntrack_alter_reply() if there are no
expectations.

nfs_writepage() refuses to write back mapped pages at all on the page
reclaim path, causing systems to get locked up when there's a lot of dirty
mmapped data around.  The patch changes NFS so that it will start I/O
against these pages.

The code as it stands is designed to defer writeout to pdflush which can do
larger, more efficient I/Os.  But there shouldn't be much traffic by this
path, and going slow is better than not going at all.

VIA chipsets are broken and don't work with IOMMU enabled. For some mysterious
reason (the IOMMU logic is actually in the CPU) they manage to corrupt all
data going through the aperture to PCI devices.

There was a workaround previously that enabled the slower softmmu when VIA is 
detected on the normal IOMMU path (when there is more than 3GB of memory). But
CONFIG_IOMMU_DEBUG took a short cut that was not handled, which ended up with 
VIA systems not booting when this option is enabled.

This patch enables the workaround with CONFIG_IOMMU_DEBUG/iommu=force too
