An earlier regression fix for the mxb driver (V4L/DVB: saa7146_vv: fix
regression where v4l2_device was registered too late) caused a new
regression in the av7110 driver.
Reverted the old fix and fixed the problem in the mxb driver instead.
Tested on mxb and budget-av cards.
The real problem is that the saa7146 framework has separate probe()
and attach() driver callbacks which should be rolled into one. This
is now done for the mxb driver, but others should do the same. Lack
of hardware makes this hard to do, though. I hope to get hold of some
hexium cards and then I can try to improve the framework to prevent
this from happening again.

As part of upstream merge, set_params() function was removed from isif.c.
This requires removal of BUG_ON() and check for set_params ptr in
vpfe_capture.c. Without this kernel crash dump is seen while bootup on DM365
Also made following changes:-
1) converted error messages to debug messages since it is not right to flood
the console with error messages for user mistakes.
2) returns -EINVAL if ioctl is not supported

Reimplement stop_machine using cpu_stop. As cpu stoppers are
guaranteed to be available for all online cpus,
stop_machine_create/destroy() are no longer necessary and removed.
With resource management and synchronization handled by cpu_stop, the
new implementation is much simpler. Asking the cpu_stop to execute
the stop_cpu() state machine on all online cpus with cpu hotplug
disabled is enough.
stop_machine itself doesn't need to manage any global resources
anymore, so all per-instance information is rolled into struct
stop_machine_data and the mutex and all static data variables are
removed.
The previous implementation created and destroyed RT workqueues as
necessary which made stop_machine() calls highly expensive on very
large machines. According to Dimitri Sivanich, preventing the dynamic
creation/destruction makes booting faster more than twice on very
large machines. cpu_stop resources are preallocated for all online
cpus and should have the same effect.

With fa35b4926, I broke a lot of PNP resource assignment. That commit made
PNPACPI include bridge windows as PNP resources, and PNP resource assignment
treats any enabled overlapping PNP resources as conflicts. Since PCI host
bridge windows typically include most of the I/O port space, this makes PNP
port assigments fail.
The PCI host bridge driver will eventually use those PNP window resources,
so we should make PNP ignore them when checking for conflicts.

Multiple Lenovo ThinkPad models with Intel Core i5/i7 CPUs can
successfully suspend/resume once, and then hang on the second s/r
cycle.
We got confirmation that this was due to a BIOS defect. The BIOS
did not properly set SCI_EN coming out of S3. The BIOS guys
hinted that The Other Leading OS ignores the fact that hardware
owns the bit and sets it manually.
In any case, an existing DMI table exists for machines where this
defect is a known problem. Lenovo promise to fix their BIOS, but
for folks who either won't or can't upgrade their BIOS, allow
Linux to workaround the issue.

Confirmed by numerous testers in the launchpad bug that using
acpi_sleep=sci_force_enable fixes the issue. We add the machines
to acpisleep_dmi_table[] to automatically enable this workaround.

There's nastyness in the way we currently handle barriers (and
discards): They're effectively filesystem commands, but they get
processed as BLOCK_PC commands. Unfortunately BLOCK_PC commands are
taken by SCSI to be SG_IO commands and the issuer expects to see and
handle any returned errors, however trivial. This leads to a huge
problem, because the block layer doesn't expect this to happen and any
trivially retryable error on a barrier causes an immediate I/O error
to the filesystem.
The only real way to hack around this is to take the usual class of
offending errors (unit attentions) and make them all retryable in the
case of a REQ_HARDBARRIER. A correct fix would involve a rework of
the entire block and SCSI submit system, and so is out of scope for a
quick fix.

Some arrays are giving I/O errors with ext3 filesystems when
SYNCHRONIZE_CACHE gets a UNIT_ATTENTION. What is happening is that
these commands have no retries, so the UNIT_ATTENTION causes the
barrier to fail. We should be enable retries here to clear any
transient error and allow the barrier to succeed.

Some FSC hardware monitoring chips (Syleus at least) doesn't like
quick writes we typically use to probe for I2C chips. Use a regular
byte read instead for the address they live at (0x73). These are the
only known chips living at this address on PC systems.
For clarity, this fix should not be needed for kernels 2.6.30 and
later, as we started instantiating the hwmon devices explicitly based
on DMI data. Still, this fix is valuable in the following two cases:
* Support for recent FSC chips on older kernels. The DMI-based device
instantiation is more difficult to backport than the device support
itself.
* Case where the DMI-based device instantiation fails, whatever the
reason. We fall back to probing in that case, so it should work.

Receiving small packet(s) in a fast pace leads to not receiving any
packets at all after some time.
After ethernet packet(s) arrived the receive descriptor is incremented
by the number of frames processed. If another packet arrives while
processing, this is processed in another call of ep93xx_rx. This
second call leads that too many receive descriptors getting released.
This fix increments, even in these case, the right number of processed
receive descriptors.
