io_mapping_create_wc can return NULL on error and io_mapping_free() should be
called on one of the error-cleanup path.

With (some) Technisat cards you cannot run multiple DVB applications
in parallel and switch the channel at the same time.
There seems to be a problem on the interfaces or even inside the flexcop-device
that can't handle interruption on the streaming interface.
This patch adds a watchdog to check whether data is supposed to come in
(streaming PIDs are requested) and if no data is seen within 400ms (default) it
resets the streaming/pid-filtering hardware.
This patch is urgently needed to support the rev 2.8 of the hardware and solves
problem occassionally seen on older hardware.

As explained in "Writing an ALSA driver" (T. Iwai), audio drivers should
set the struct device for the card before registering the card instance.
This will add the correct /sys/class/sound/cardN/device symlink, so HAL
can see the device and ConsoleKit sets its ACL permissions for the
logged-in user.
For em28xx audio capture cards found e.g. in Hauppauge WinTV-HVR-900 (R2),
this patch fixes errors like:
ALSA lib pcm_hw.c:1429:(_snd_pcm_hw_open) Invalid value for card

commit 176bf2e0f10ecf1d20a97db3bd5bb2e6ba0b5668 ("physmap: fix leak of
memory returned by parse_mtd_partitions") deals with a memory leak and
frees the pointer array of mtd_partition after the call to
add_mtd_partitions(). the problem is that mtd_table[x]->name still points
to the freed memory.
Aldo physmap_flash_remove() should call del_mtd_partitions() or
del_mtd_device() only once.

The PCIe port driver currently sets the PCIe AER error reporting bits for
any root or switch port without first checking to see if firmware will grant
control. This patch moves setting these bits to the AER service driver
aer_enable_port routine. The bits are then set for the root port and any
downstream switch ports after the check for firmware support (aer_osc_setup)
is made. The patch also unsets the bits in a similar fashion when the AER
service driver is unloaded.

Prakash reported that his c51-mcp51 ondie sound card doesn't work with
MSI. But if he hacks out the HT-MSI quirk, MSI works fine.
So this patch reworks the nv_msi_ht_cap_quirk(). It will now only
enable ht_msi on own its root device, avoiding enabling it on devices
following that root dev.

If reset_devices is set for kexec, then cciss will delay 30 seconds
since the old 5i controller _may_ need that long to recover. Replace
the long sleep with incremental sleep and tests to reduce the 30 seconds
to worst case for 5i, so that other controllers will proceed quickly.

It needs to happen before any firewire driver actually registers itself,
and that was previously handled by having the Makefile list the core
ieee1394 files before the drivers.
But now there are firewire drivers in drivers/media, and the Makefile
games aren't enough. So just make ieee1394_init happen earlier in the
init sequence, the way all other bus layers already do.

These devices are generally used with ATA anyway and it seems that some
ATAPI will need us to issue the right number of words. Therefore as we
can't switch mid burst on VLB devices we should only use 32bit I/O for
suitable block sizes.

With 32bit PIO we can use the posted write buffers, but only for 32bit I/O
cycles. This means we must disable the FIFO for ATAPI where a final 16bit
cycle may occur.
Rework the FIFO logic so that we disable the FIFO then selectively
re-enable it when we set the timings on AMD devices. Also fix a case
where we scribbled on PCI config 0x41 of Nvidia chips when we shouldn't.

For some reason, sata_mv doesn't clear interrupt status during init
when it's running on an SoC host adapter. If the bootloader has
touched the SATA controller before starting Linux, Linux can end up
enabling the SATA interrupt with events pending, which will cause the
interrupt to be marked as spurious and then be disabled, which then
breaks all further accesses to the controller.
This patch makes the SoC path clear interrupt status on init like in
the non-SoC case.

Hibernation didn't work for me since I started to use IT8212 controller.
I did some debugging (booting with no_console_suspend init=/bin/sh).
Found that resume fails (2.6.28) with "serial number mismatch 'some
garbage' != 'some other garbage'" and "revalidation failed" messages.
That's because the controller firmware fills different serial number in
the IDENTIFY every boot.
The patch below fixes the resume simply clearing the serial number. The
proper fix would be probably to fill in the serial number of the RAID
volume instead. I assume that there must be something like that stored on
the drives but I don't know where.
Fix resume on pata_it821x RAID volume by clearing the serial number in
IDENTIFY data, which is otherwise different on each boot.

During host driver module removal del_gendisk() results in a final
put on drive->gendev and freeing the drive by drive_release_dev().
Convert device drivers from using struct kref to use struct device
so device driver's object holds reference on ->gendev and prevents
drive from prematurely going away.
Also fix ->remove methods to not erroneously drop reference on a
host driver by using only put_device() instead of ide*_put().

Fix missing parentheses so PIO/DMA timings for master device on the
second channel are programmed correctly (IOW "8 0 24 16" offset values
should be used instead of the current "8 0 16 16").
[ The bug went unnoticed because after PIO/DMA timings get programmed
incorrectly for the third device they are overwritten with timings
for the fourth device and since BIOS should also program timings for
the third device everything should work fine until suspend/resume
cycle or user requested transfer mode changes. ]

- ide=nodma is no longer valid.
drivers/ide/Kconfig
- The module is ide-core.ko not ide.
drivers/ide/ide.c
- It took me a while to figure out what the arguments %d.%d:%d to nodma
module parameter ment, so I added a comment to each.
- Added a comment to each of the sscanf lines.
- There is a bug, if j is 0 it would previously clear all the other bits
except the current device, changed in three different places.
mask &= (1 << i) should be mask &= ~(1 << i).

However we still have another issue with ioremap_wc not falling back
properly or somehow doing something else stupid, this probably needs
to be tracked down.

edid->revision == 0 should be valid (at least, so the error message
indicates. :) and wikipedia seems to indicate that EDID 1.0 existed.
We can dump the entire check, since edid->revision is a u8, so
it can't ever be less than 0.
Marko reports in RH bz#476735 that his monitor claims to be
EDID 1.0, and therefore hits the check and is stuck at 800x600 because
of it.

The first time we install a mode, the vblank will be disabled for a pipe
and so drm_vblank_get() in drm_vblank_pre_modeset() will fail. As we
unconditionally call drm_vblank_put() afterwards, the vblank reference
counter becomes unbalanced.

In some cases we may receive a mode config that has a different
CRTC<->encoder map that the current configuration. In that case, we
need to disable any re-routed encoders before setting the mode,
otherwise they may not pick up the new CRTC (if the output types are
incompatible for example).

We've seen cases in the wild where the VBT sync data is wrong, so add
some code to fix it up in that case, taking care to make sure that the
