One of the issues with the ASoC v1 API which has been addressed in the
ASoC v2 work that Liam Girdwood has done is that the ALSA card provided
by ASoC is distributed around the ASoC structures. For example, machine
wide data such as the struct snd_card are maintained as part of the
CODEC data structure, preventing the use of multiple codecs. This has
been addressed by refactoring the data structures so that all the data
for the ALSA card is contained in a single structure snd_soc_card which
replaces the existing snd_soc_machine and snd_soc_device.
Begin the process of backporting this by renaming struct snd_soc_machine
to struct snd_soc_card, better reflecting its function and bringing it
closer to standard ALSA terminology.

Impact: makes device isolation the default for AMD IOMMU
Some device drivers showed double-free bugs of DMA memory while testing
them with AMD IOMMU. If all devices share the same protection domain
this can lead to data corruption and data loss. Prevent this by putting
each device into its own protection domain per default.

This adds a driver to the accelerometer sensor found in several HP
laptops (under the commercial names of "HP Mobile Data Protection System
3D" and "HP 3D driveguard"). It tries to have more or less the same
interfaces as the hdaps and other accelerometer drivers: in sysfs and as
a joystick.
This driver was first written by Yan Burman. Eric Piel has updated it
and slimed it up (including the removal of an interface to access to the
free-fall feature of the sensor because it is not reliable enough for
now). Pavel Machek removed few more features and switched locking from
semaphore to mutex.
Several people have contributed to the database of the axes.

With this change, control file 'freezer.state' doesn't exist in root
cgroup, making root cgroup unfreezable.
I think it's reasonable to disallow freeze tasks in the root cgroup. And
then we can avoid fork overhead when freezer subsystem is compiled but not
used.
Also make writing invalid value to freezer.state returns EINVAL rather
than EIO. This is more consistent with other cgroup subsystem.

Commit d0fc2eaaf4 "powerpc/fsl: Refactor

booting-without-of.txt into separate files. Having them all in one file
was a frequent source of merge conflicts.
However, in the next merge, 49997d7515, there
was another conflict. Some of the bindings removed from

dts-bindings were kept as well.

If an ACPI graphics device supports backlight brightness functions (cmp. with
latest ACPI spec Appendix B), let the ACPI video driver control backlight and
switch backlight control off in vendor specific ACPI drivers (asus_acpi,
thinkpad_acpi, eeepc, fujitsu_laptop, msi_laptop, sony_laptop, acer-wmi).
Currently it is possible to load above drivers and let both poke on the
brightness HW registers, the video and vendor specific ACPI drivers -> bad.
This patch provides the basic support to check for BIOS capabilities before
driver loading time. Driver specific modifications are in separate follow up
patches.

FAT has the ATTR_RO (read-only) attribute. But on Windows, the ATTR_RO
of the directory will be just ignored actually, and is used by only
applications as flag. E.g. it's setted for the customized folder by
Explorer.
http://msdn2.microsoft.com/en-us/library/aa969337.aspx
This adds "rodir" option. If user specified it, ATTR_RO is used as
read-only flag even if it's the directory. Otherwise, inode->i_mode
is not used to hold ATTR_RO (i.e. fat_mode_can_save_ro() returns 0).

Impact: add new generic io_map_*() APIs
Graphics devices have large PCI apertures which would consume a significant
fraction of a 32-bit address space if mapped during driver initialization.
Using ioremap at runtime is impractical as it is too slow.
This new set of interfaces uses atomic mappings on 32-bit processors and a
large static mapping on 64-bit processors to provide reasonable 32-bit
performance and optimal 64-bit performance.
The current implementation sits atop the io_map_atomic fixmap-based
mechanism for 32-bit processors.
This includes some editorial suggestions from Randy Dunlap for

Impact: build fix on non-lockdep architectures
Some architectures do not support a way to read the irq flags that
is set from "local_irq_save(flags)" to determine if interrupts were
disabled or enabled. Ftrace uses this information to display to the user
if the trace occurred with interrupts enabled or disabled.
Besides the fact that those archs that do not support this will fail to
compile, unless they fix it, we do not want to have the trace simply
say interrupts were not disabled or they were enabled, without knowing
the real answer.
This patch adds a 'X' in the output to let the user know that the
architecture they are running on does not support a way for the tracer
to determine if interrupts were enabled or disabled. It also lets those
same archs compile with tracing enabled.
