When the usb-storage module forces sdev->scsi_level to SCSI_2, it should
also force starget->scsi_level to the same value. Otherwise, the SCSI
layer may attempt to issue SCSI-3 commands to the device, such as REPORT
LUNS, which it cannot handle. This can prevent the device from working
with Linux.
The AMS Venus DS3 DS2316SU2S SATA-to-SATA+USB enclosure, based on the
Oxford Semiconductor OXU921S chip, requires this patch to function
correctly on Linux. The enclosure reports a SCSI-3 SPC-2 command set
level, but does not correctly handle the REPORT LUNS SCSI command -
probably due to a bug in its firmware.
It seems likely that other USB storage enclosures with similar bugs will
also benefit from this patch.

The g5 thermal control for liquid cooled machines has a small bug, when
the temperatures gets too high, it boosts all fans to the max, but
incorrectly sets the liquids pump to the min instead of the max speed,
thus causing the overtemp condition not to clear and the machine to shut
down after a while. This fixes it to set the pumps to max speed instead.
This problem might explain some of the reports of random shutdowns that
some g5 users have been reporting in the past.
Many thanks to Marcus Rothe for spending a lot of time trying various
patches & sending log logs before I found out that typo. Note that
overtemp handling is still not perfect and the machine might still
shutdown, that patch should reduce if not eliminate such occcurences in
"normal" conditions with high load. I'll implement a better handling
with proper slowing down of the CPUs later.

In the scenario that a link was broken, the devloss timer for each
rport was expire at roughly the same time, causing lots of "delete"
workqueue items being queued. Depth is dependent upon the number of
rports that were on the link.
The rport target remove calls were calling flush_scheduled_work(),
which would interrupt the stream, and start the next workqueue item,
which did the same thing, and so on until recursion depth was large.
This fix stops the recursion in the initial delete path, and pushes it
off to a host-level work item that reaps the dead rports.

Every framebuffer driver relies on the assumption that the set_par()
function of the driver is called before drawing functions and other
functions dependent on the hardware state are executed.
Whenever you switch from X to a framebuffer console for the very first
time, there is a chance that a broken X system has _not_ set the mode to
KD_GRAPHICS, thus the vt and framebuffer code executes a screen redraw and
several other functions before a set_par() is executed. This is believed
to be not a bug of linux but a bug of X/xdm. At least some X releases used
by SuSE and Debian show this behaviour.
There was a 2nd case, but that has been fixed by Antonino Daplas on
10-dec-2005.
This patch allows drivers to set a flag to inform fbcon_switch() that they
prefer a set_par() call on every console switch, working around the
problems caused by the broken X releases.
The flag will be used by the next release of cyblafb and might help other
drivers that assume a hardware state different to the one used by X.
As the default behaviour does not change, this patch should be acceptable
to everybody.

This has been broken for months. On resume, we call acpi_pci_link_set()
with interrupts off, so we get a warning when we try to do a kmalloc of non
atomic memory. The actual allocation is just 2 long's (plus extra byte for
some reason I can't fathom), so a simple conversion to GFP_ATOMIC is
probably the safest way to fix this.
The error looks like this..

The bd62266319 commit broke the UCB1x00
touchscreen driver since the idev structure was assumed to be into the ts
structure, simply casting the former to the later in a couple places.
This patch fixes those, and also cache the idev pointer between multiple
calls to input_report_abs() to avoid growing the compiled code needlessly.

The IPMI specifcation says the generator ID is 0x20, but that is for bits
7-1. Bit 0 is set to specify it is a software event. The correct value is
0x41. Without this fix, panic events written into the System Event Log
appear to come from an "unknown" generator, rather than from the kernel.

This undoes the put_disk patch I sent in before.
If I had been paying attention I would have seen that we call put_disk
from free_hba during driver unload. That's the only time we want to
call it. If it's called from deregister disk we may remove the
controller (cNd0) unintentionally.

This adds a timestamp field to the events sent via the process event
connector. The timestamp allows listeners to accurately account the
duration(s) between a process' events and offers strong means with which
to determine the order of events with respect to a given task while also
avoiding the addition of per-task data.
This alters the size and layout of the event structure and hence would
break compatibility if process events connector as it stands in 2.6.15-rc2
were released as a mainline kernel.

The scsi_library routines don't correctly set DMA_NONE when
req->data_len is zero (instead they check the command type first, so
if it's write, we end up with req->data_len == 0 and direction as
DMA_TO_DEVICE which confuses some drivers)

The eh_action semaphore in scsi_eh_send_command is cleared after a
command timeout. The command is subsequently aborted and the abort
will try to call scsi_done() on it. Unfortunately, the scsi_eh_done()
routine unconditinally completes the semaphore (which is now null).
Fix this race by makiong the scsi_eh_done() routine check that the
semaphore is non null before completing it (mirroring the ordinary
command done/timeout logic).
