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.Signed-off-by: Joerg Roedel

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.Signed-off-by: Li Zefan

Commit d0fc2eaaf4c56a95f5ed29b6bfb609e19714fc16 "powerpc/fsl: Refactor
device bindings" split out a number of device bindings from
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, 49997d75152b3d23c53b0fa730599f2f74c92c65, there
was another conflict. Some of the bindings removed from
booting-without-of.txt were mistakenly added back in and the copies in
dts-bindings were kept as well.This patch re-removes "Freescale Display Interface" and "Freescale on board
FPGA" and fixes the table of contents.Signed-off-by: Trent Piepho

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."acpi_backlight=vendor"

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).Signed-off-by: OGAWA Hirofumi
