0263869760 Staging: comedi: Altered the way printk is used in 8255.c
This patch moves around the use of printk calls in 8255.c to include accurate
logging levels and in turn fixes a few warnings from checkpatch.

5763dcab5c staging: iio: adis16350 and similar IMU driver
This version has the right part number in the commit message.
Whilst technically the part I listed last time is also supported
by the driver, the commit message might have caused confusion.

Another driver from Barry at Analog.  Again, I've lifted
if from the blackfin tree and done the usual sparse
and checkpatch fixes + the abi changes.  I actually
have one of these, so am particularly pleased to see
it supported!

81b77f94a1 Staging: iio: max1363 Fix two bugs in single_channel_from_ring
This patch contains fixes for the two bugs Michael pointed
out last week.  As the other suggestion Michael made is
not a bug fix (just a much more sensible way of handling
things), I'll do that as a separate patch soon.

The bugs were introduced with the abi changes.

ba2450b89b Staging: comedi: Kconfig dependancy fixes
There are three minor changes I would like to do on my last patch:

* Comedi is formally not dependant on any hardware, e.g. it is possible
  to use comedi_test without (PCI || PCMCIA || PCCARD || USB || ISA)
* comedi_parport is not dependant on PARPORT_PC.
* indirect ni_mio_cs (16-bit PCMCIA) dependancy on mite PCI-chip may
  confuse users, thus changing COMEDI_NI_TIO depends on COMEDI_MITE
  to select COMEDI_MITE.

f1d7dbbef5 Staging: comedi: new Kconfig and Makefiles, drivers grouped by bustype.
PC/104-drivers went into ISA,
PC/104+ went into PCI,
Drivers without a bustype went into "misc".
In doubt drivers supporting both ISA/PCI went into PCI.
Drivers without any detailed hardware info went into ISA, e.g. fl512.c
Some NI drivers are used by other NI drivers from different bustypes
are grouped seperately in NI_COMMON.

[tweaked by gregkh to handle the new driver recently added]

57c8a45664 can: Fix SJA1000 command register writes on SMP systems
The SJA1000 command register is concurrently written in the rx-path to free
the receive buffer _and_ in the tx-path to start the transmission.

The SJA1000 data sheet, 6.4.4 COMMAND REGISTER (CMR) states:
"Between two commands at least one internal clock cycle is needed in
order to proceed. The internal clock is half of the external oscillator
frequency."

On SMP systems the current implementation leads to a write stall in the
tx-path, which can be solved by adding some general locking and some time
to settle the write_reg() operation for the command register.

Thanks to Klaus Hitschler for the original fix and detailed problem
description.

This patch applies on net-2.6 and (with some offsets) on net-next-2.6 .

ac1ececea9 i7core_edac: Add support for X5670
As reported by Vernon Mauery <vernux@us.ibm.com>, X5670 (Westmere-EP) uses a

it.

Those are the PCI ID's on this new chipset:

fe:06.3 0600: 8086:2db3 (rev 02)
(as usual, the same PCI devices repeat at ff: bus)

The PCI device 8086:2c70 is shown as:

fe:00.0 Host bridge: Intel Corporation QuickPath Architecture Generic
Non-core Registers (rev 02)

So, for this device to be recognized, it is only a matter of adding this
new PCI ID to the driver.

8a311e179e Always call i7core_[ur]dimm_check_mc_ecc_err
This fixes an error in function i7core_check_error

In commit ca9c90ba09 which converts the
driver to use double buffering, there is a change in the logic.  Before,
if mce_count was zero, it skipped over a couple of statements and
finished out with a call to the *check_mc_ecc_err function.  The current
code checks to see if mce_count is 0 and then exits.

This change reverts the behavior back to the original where if there are
no errors to report, we skip to the end and call the *check_mc_ecc_err
function.

This fix allows the driver to work again on my Nehalem based blades
again.

cd874237d9 mtd: mtdchar: Do not corrupt backing device of device node inode
We cannot modify file->f_mapping->backing_dev_info, because it will corrupt
backing device of device node inode, since file->f_mapping is equal to
inode->i_mapping (see __dentry_open() in fs/open.c).

Let's introduce separate inode for MTD device with appropriate backing
device.

[dwmw2: Refactor to keep it all entirely within mtdchar.c; use iget_locked()]

If omapdss_dsi_display_enable() failed the DSI bus was left locked. Also
if the operation failed later omapdss_dsi_display_disable() would get

f49a951f8a OMAP: DSS2: Make partial update width even
There are some strange problems with DSI and updates with odd widths. One
particular problem is that HS TX timeout triggers easily with updates with
odd widths.

This patch makes the updates widths even, circumventing the problem. There
should be no ill side effects with increasing the update area slightly to
make the width even.

a8ab5d58b0 HID: hidraw: Use Interrupt Endpoint for OUT Transfers if Available
This patch makes the hidraw driver use the first Interrupt OUT endpoint for
HID transfers to the device if such an endpoint exists. This is consistent
with the behavior of the hiddev driver, and the logic is similar.

From the USB HID specification:

   The Interrupt Out pipe is optional. If a device declares an Interrupt Out
   endpoint then Output reports are transmitted by the host to the device
   through the Interrupt Out endpoint. If no Interrupt Out endpoint is
   declared then Output reports are transmitted to a device through the
   Control endpoint, using Set_Report(Output) requests.

4bff51711c drm/radeon/kms/pm: fix r6xx+ profile setup
This patch is a combination of the previous two profile
patches, but without the index bugs.  It cleans up and
fixes some issues with pm profile setup on r6xx chips.
Some tables have different orderings for the power states,
also, r600 only has 1 clock mode per power state. On
desktop cards there are no battery modes, so the low and high
power states are the same.  For the low profile case, choose
the lower clock mode.

ce8f53709b drm/radeon/kms/pm: rework power management
- Separate dynpm and profile based power management methods.  You can select the pm method
  by echoing the selected method ("dynpm" or "profile") to power_method in sysfs.
- Expose basic 4 profile in profile method
  "default" - default clocks
  "auto" - select between low and high based on ac/dc state
  "low" - DC, low power mode
  "high" - AC, performance mode
  The current base profile is "default", but it should switched to "auto" once we've tested
  on more systems.  Switching the state is a matter of echoing the requested profile to
  power_profile in sysfs.  The lowest power states are selected automatically when dpms turns
  the monitors off in all states but default.
- Remove dynamic fence-based reclocking for the moment.  We can revisit this later once we
  have basic pm in.
- Move pm init/fini to modesetting path.  pm is tightly coupled with display state.  Make sure
  display side is initialized before pm.
- Add pm suspend/resume functions to make sure pm state is properly reinitialized on resume.
- Remove dynpm module option.  It's now selectable via sysfs.
