* | Add c2 port supportRodolfo Giometti2008-11-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | C2port implements a two wire serial communication protocol (bit banging) designed to enable in-system programming, debugging, and boundary-scan testing on low pin-count Silicon Labs devices. Currently this code supports only flash programming through sysfs interface but extensions shoud be easy to add.

* | LIS3LV02Dx Accelerometer driverPavel Machek2008-11-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | freezer_cg: disable writing freezer.state of root cgroupLi Zefan2008-11-12
|/ | | | | | | | | | | | | | | | | | | | | 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.

For all the GPEs and Fixed Events, 1. ACPI_EVENT_FLAG_HANDLE is cleared, it's an "invalid" ACPI event. 2. Both ACPI_EVENT_FLAG_HANDLE and ACPI_EVENT_FLAG_DISABLE are set, it's "disabled". 3. Both ACPI_EVENT_FLAG_HANDLE and ACPI_EVENT_FLAG_ENABLE are set, it's "enabled". 4. Both ACPI_EVENT_FLAG_HANDLE and ACPI_EVENT_FLAG_WAKE_ENABLE are set, it's "wake_enabled". Among other things, this prevents incorrect reporting of ACPI events as being "invalid" when it's really just (temporarily) "disabled".

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.

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).

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.

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. Signed-off-by: Steven Rostedt <srostedt@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
