Attached. Also fixed some __init / __devinit and __exit / __devexit
attributes. Although, would be good to have something like

#ifdef CONFIG_HOTPLUG_PCI
#define __pcidevinit
#define __pcidevinitdata
#define __pcidevexit
#define __pcidevexitdata
#else
#define __pcidevinit __init
#define __pcidevinitdata __initdata
#define __pcidevexit __exit
#define __pcidevexitdata __exitdata
#endif

Some SCSI-IDE cdrom drives take up to 15 seconds to respond following
an abort being issued to them. This patch changes ipr to only send
a cancel all to a device as part of request sense processing when
the device is running tagged command queueing.
Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

The following patch fixes a hang that occurs when an abort
is issued by the midlayer. The hang is the result of overriding
a field in the union of the ipr_cmd struct. It is fixed by moving
this pointer outside of the union, since it is not mutually exclusive
with the other fields in the union.

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

This is a fix for when we encounter an alias during insert. When that
happens we move the request to dispatch, but it may happen that this
request is also the ->last_merge hint. So we may attempt to merge with
this later, when it's either in progress or already freed. Rearrange the
logic a bit so we clear the merge hint there as well. It looks more
complex than it is, the only real code change is the addition of a
cfq_remove_merge_hints() in cfq_dispatch_sort().

This cset adds the code to handle the hardware vector floating point
unit found on some ARM926 and later CPUs.  The hardware provides
an implementation for the common cases, and bounces exceptions for
other cases, which have to be handled in software, and signalling
SIGFPE as appropriate.

Add a user_struct pointer to the sigqueue structure.  Charge sigqueue
allocation and destruction to the user_struct rather than a global pool.  This
per user rlimit accounting obsoletes the global queued_signals accouting.

The patch as charges the sigqueue struct allocation to the queue that it's
pending on (the receiver of the signal).  So the owner of the queue is charged
for whoever writes to it (much like quota for a 777 file).

The patch started out charging the task which allocated the sigqueue struct.
In most cases, these are always the same user (permission for sending a
signal), so those cases are moot.  In the cases where it isn't the same user,
it's a privileged user sending a signal to another user.

It seems wrong to charge the allocation to the privleged user, when the other
user could block receipt as long as it feels.  The flipside is, someone else
can fill your queue (expectation is that someone else is privileged).  I think
it's right the way it is.  The change to revert is very small.
