Fixes a regression from commit 0f8e0d9a, "dlm: allow multiple lockspace creates". An extraneous 'else' slipped into a code fragment being moved from release_lockspace() to dlm_release_lockspace(). The result of the unwanted 'else' is that dlm threads and structures are not stopped and cleaned up when the final dlm lockspace is removed. Trying to create a new lockspace again afterward will fail with "kmem_cache_create: duplicate cache dlm_conn" because the cache was not previously destroyed. Signed-off-by:

The HDQ/1-Wire module of TI OMAP2430/3430 platforms implement the hardware protocol of the master functions of the Benchmark HDQ and the Dallas Semiconductor 1-Wire protocols. These protocols use a single wire for communication between the master (HDQ/1-Wire controller) and the slave (HDQ/1-Wire external compliant device).

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.

We're working with an AT91SAM9263 Rev B in our design and I experienced some inconsistency in spi-based touchscreen usage between our board and the Atmel evaluation kit we have that runs on a Rev A chip. The data was apparently delayed by 1 byte and got ridiculous data out of the touchscreen driver, very strange. As everything looked normal in the spi, touchscreen and dma logs, I contacted the Atmel support and they triggered me on a new HW bug that appeared in the Rev B SPI controller. The problem is that the SPI controller on the Rev B needs that the software reset is performed two times so that it's performed correctly. Applying the patch below solves the issue on my Rev B board. I've tested it as well on my Rev A evaluation kit and it has apparently no unwanted side effect, things continue to work as expected. Signed-off-by:

lockdep warns about following message at boot time on one of my test machine. Then, schedule_on_each_cpu() sholdn't be called when the task have mmap_sem. Actually, lru_add_drain_all() exist to prevent the unevictalble pages stay on reclaimable lru list. but currenct unevictable code can rescue unevictable pages although it stay on reclaimable list. So removing is better. In addition, this patch add lru_add_drain_all() to sys_mlock() and sys_mlockall(). it isn't must. but it reduce the failure of moving to unevictable list. its failure can rescue in vmscan later. but reducing is better. Note, if above rescuing happend, the Mlocked and the Unevictable field mismatching happend in /proc/meminfo. but it doesn't cause any real trouble.

__register_kprobe() can be preempted after checking probing address but before module_text_address() or try_module_get(), and in this interval the module can be unloaded. In that case, try_module_get(probed_mod) will access to invalid address, or kprobe will probe invalid address. This patch uses preempt_disable() to protect it and uses __module_text_address() and __kernel_text_address(). Signed-off-by:

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:
