6ecb6f25d3 pata_hpt366: reimplement mode programming
Reimplement mode programming logic of pata_hpt366 such that it's
identical to that of IDE hpt366 driver.  The differences were...

* pata_hpt366 used 0xCFFF8FFFF to mask pio modes and 0x3FFFFFFF dma
  modes.  IDE hpt366 uses 0xC1F8FFFF for PIO, 0x303800FF for MWDMA and
  0x30070000 for UDMA.

* pata_hpt366 doesn't set 0x08000000 for PIO unless it's already set
  and always turns it on for MWDMA/UDMA.  IDE hpt366 doesn't bother
  with the bit.  It always uses what was there.

* IDE hpt366 always clears 0xC0000000.  pata_hpt366 doesn't.

2852bcf7c1 ata_piix: save, use saved and restore IOCFG
Certain ACPI implementations mess up IOCFG on _STM making libata
detect cable type incorrectly after a suspend/resume cycle.  This
patch makes ata_piix save IOCFG on attach, use the saved value for
things which aren't dynamic and restore it on detach so that the next
driver also gets the BIOS initialized value.

This patch contains the following changes.

* makes ich_pata_cable_detect() use saved_iocfg.

* make piix_iocfg_bit18_quirk() take @host and use saved_iocfg.

* hpriv allocation moved upwards to save iocfg before doing anything
  else.

This fixes bz#11879.  Andreas Mohr reported and diagnosed the problem.

c7e26631d2 w1: allow master IO commands
This small patchset extendes existing commands with reset, master IO and
status messages.  Reset is used to reset the bus for given master device,
master IO command allows to initiate IO against bus itself not selecting
slave device first, which can be used to probe the device for example.
And status messages carry command completion status back to the userspace
(namely very useful to get -ENODEV from when requested device was not
found).

Great thanks to Paul Alfille of OWFS for testing and commands suggestions.

This patch:

Allow starting of IO not against already found slave devices, but against
the bus itself, which can be used for example to probe devices.

have alarms (DS1337).

this exports a file to allow usermode to interact with xenbus/xenstore.

a xenfs filesystem which can be mounted there.

NWP stands for network processor and it is part of the QPACE - Quantum
Chromodynamics Parallel Computing on the Cell Broadband Engine project.
The implementation is a lightweight uart implementation with the focus
to consume as little resources as possible and it is connected to a

e32fadc4c2 V4L/DVB (10190): cx88: Fix some Kbuild troubles
As Randy Dunlap <randy.dunlap@oracle.com> reported, cx88 has some compilation issues:

drivers/built-in.o: In function `cx88_call_i2c_clients':
(.text+0x20af17): undefined reference to `videobuf_dvb_get_frontend'
drivers/built-in.o: In function `cx8802_probe':
cx88-mpeg.c:(.devinit.text+0x268c4): undefined reference to `videobuf_dvb_alloc_frontend'
cx88-mpeg.c:(.devinit.text+0x268ea): undefined reference to `videobuf_dvb_dealloc_frontends'

With those configs:

CONFIG_VIDEO_CX88=y
CONFIG_VIDEO_CX88_BLACKBIRD=y
CONFIG_VIDEO_CX88_DVB=m
CONFIG_DVB_CORE=m

After carefully examining the code, with the current code, several cx88 drivers
(cx8800, cx8802, cx88_dvb and cx88_blackbird) should be compiled as a module,
if one of them is marked as such. Just fixing Kconfig could create a very complex
set of rules. Also, this hides a problem with the current approach where the dvb
functionality weren't confined inside dvb module.

What happens is that:
	- cx88-i2c (part of cx8800) has some special rules if DVB;
	- cx88-mpeg (cx8802 module) has also part of DVB init code;
	- cx88-dvb has the rest of the dvb code;
	- cx88-blackbird can be used with cx88-mpeg, having cx88-dvb or not.

So, instead of doing some tricks at Kconfig and wait for a next breakage,
this patch moves the dvb code inside cx88-i2c and cx88-mpeg into cx88-dvb.

Another problem is that cx8802 were being compiled, even without cx88-dvb
and cx88-blackbird modules.

While on this code, let's fix also a reported problem:

A solution for the issue were proposed here:

Thanks to Randy, Andy, Gregoire and Thomas for helping us to detect
and solve the issues.

571d864c68 V4L/DVB (10189): dm1105: Fix build with INPUT=m and DVB_DM1105=y
As reported by Randy Dunlap <randy.dunlap@oracle.com>:

With CONFIG_INPUT=m and CONFIG_DVB_DM1105=y:

drivers/built-in.o: In function `input_sync':
dm1105.c:(.text+0x120c33): undefined reference to `input_event'
drivers/built-in.o: In function `dm1105_emit_key':
dm1105.c:(.text+0x120c6c): undefined reference to `input_event'
dm1105.c:(.text+0x120c82): undefined reference to `input_event'
dm1105.c:(.text+0x120cb2): undefined reference to `input_event'
dm1105.c:(.text+0x120cd1): undefined reference to `input_event'
drivers/built-in.o: In function `dm1105_ir_init':
(.devinit.text+0xd8ae): undefined reference to `input_allocate_device'
drivers/built-in.o: In function `dm1105_ir_init':
(.devinit.text+0xd9f6): undefined reference to `input_register_device'
drivers/built-in.o: In function `dm1105_ir_init':

drivers/built-in.o: In function `dm1105_ir_exit':
(.devexit.text+0xcde): undefined reference to `input_unregister_device'

This is due to the lack of a dependency between dm1105 and CONFIG_INPUT

2230c3c803 V4L/DVB (10185): Use negated usb_endpoint_xfer_control, etc
This patch extends 134179823b by using
usb_endpoint_xfer_control, usb_endpoint_xfer_isoc, usb_endpoint_xfer_bulk,
and usb_endpoint_xfer_int in the negated case as well.

The semantic patch that makes this change is as follows:

439b72b69e V4L/DVB (10182): tda8290: fix TDA8290 + TDA18271 initialization
Don't call tda8290_init_tuner unless we have either a TDA8275 or TDA8275A
present. Calling this function will cause a TDA18271 to get sick, so we
should only call it when needed.
