Should clear the next pointer of the TX if we are sure that the
next TX (say NXT) will be submitted to the channel too. Overwise,
we break the chain of descriptors, because we lose the information
about the next descriptor to run. So next time, when invoke
async_tx_run_dependencies() with TX, it's TX->next will be NULL, and
NXT will be never submitted.

This patch teaches the i2c-sh_mobile driver to make use of wait irqs.
Without this patch only dte irqs are used which may lead to overruns
and cases of missing stop and extra bytes being read on the i2c bus.

Use of wait irqs forces the hardware to pause and wait until the cpu
is ready. Polling is also reworked in this patch to fix ms delay issues.

Signed-off-by: Paul Mundt <lethal@linux-sh.org>

This patch fixes a problem within the SH implementation of resume_kernel code,
that implements in assembly the bulk of preempt_schedule_irq function without
taking care of the extra code needed to handle the BKL preemptible.

The patch basically consists of removing this asm code and calling the common
C implementation (see kernel/sched.c) as other archs do.

Another change is the missing 'cli' macro invocation at the beginning of
the resume_kernel.

While doing some testing using Luca Risolia's sonix driver I noticed that
the video device did not get ACL's set to allow access by locally logged in
users, nor does it show up as a video device in lshal, causing cheese to not
see it.

This turns out to be caused by all of Luca Risolia's drivers not setting
the parent member of the video_device struct. This patch fixes this.

When using the sonixb driver in a dark room and given that the autoexposure
algorithm starts with a setting most suitable for daylight, the picture
produced by the cam may actually be 100% black leading to a avg_lum value of 0,
so an avg_lum value of 0 does not always signal an exposure settings change
(which it normally does). This patch adds a check for the really black image
case and stops dropping all frames as invalid in this case.

The following patch (based on a patch from Stephen Gildea) fixes a
regression with the LCD brightness keys on Fujitsu P8010 laptops which was
observed with the 2.6.27-rc series (basically they stopped working due to
changes within the fujitsu-laptop and video modules).  Please apply to
2.6.27-rc and acpi git.

A more complete solution for this laptop will be included in an upcoming
patch, hopefully for 2.6.28.  In the meantime this restores most
functionality for P8010 users.

Commit 88452565 ("PCI: clean up resource
alignment management") changed the resource handling to mark how a
resource was aligned on a per-resource basis.

Thus, instead of looking at the resource number to determine whether it
was a bridge resource or a regular resource (they have different
alignment rules), we should just ask the resource for its alignment
directly.

The reason this broke only cardbus resources was that for the other
types of resources, the old way of deciding alignment actually still
happened to work.  But CardBus bridge resources had been changed by
commit 934b7024 ("Fix cardbus resource
allocation") to look more like regular resources than PCI bridge
resources from an alignment handling standpoint.

When calibration against PIT fails, the warning that we print is misleading.
In a virtualized environment the VM may get descheduled while calibration
or, the check in PIT calibration may fail due to other virtualization
overheads.

The warning message explicitly assumes that calibration failed due to SMI's
which may not be the case. Change that to something proper.
