With CONFIG_IRQSOFF_TRACER the trace_hardirqs_off() function includes a call to __builtin_return_address(1). But we calltrace_hardirqs_off() from early entry code. There we have just a single stack frame. So this results in a kernel stack backchain walk that would walk beyond the kernel stack. Following the NULL terminated backchain this results in a lowcore read access. To fix this we simply call trace_hardirqs_off_caller() and pass the current instruction pointer. Signed-off-by:

Disable tracing on idle psw. Otherwise it would give us huge preempt off times for idle. Which is rather pointless. Signed-off-by:

The current virtio model on s390 has the descriptor page above the main memory. The guest virtio detection will oops if the mem= parameter is used to reduce/change the memory size. We have to use real_memory_size instead of max_pfn to detect the virtio descriptor pages. Signed-off-by:Christian Borntraeger <borntraeger@de.ibm.com>

add_active_range() expects start_pfn + size as end_pfn value, i.e. not the pfn of the last page frame but the one behind that. We used the pfn of the last page frame so far, which can lead to a BUG_ON in move_freepages(), when the kernelcore parameter is specified (page_zone(start_page) != page_zone(end_page)).

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:

Madhusudhan Chikkature authored
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 patch provides the HDQ driver to suppport TI OMAP2430/3430 platforms. Signed-off-by: Madhusudhan Chikkature<madhu.cr@ti.com> Acked-by:

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:
