Sometimes lis3 chip seems to fail to setup factory tuning at boot up. This probably happens if there is some odd power ramp down ramp up sequence for example in device restart. Set boot bit in control2 register to trig boot sequence manually and wait until it is finished. Signed-off-by:

Irqcfg moved to chip data instead of platform data. This simplifies access in interrupt handler little bit. Input device open and close functions set status for interrupt threaded handler once. Unnecessary check for interrupt source removed since it is enough that active interrupt line indicates that there was an interrupt. Signed-off-by:

Add pm_runtime support to lis3 core driver. Add pm_runtime support to lis3 i2c driver. spi and hp_accel drivers are not yet supported. Old always on functionality remains for those. For sysfs there is 5 second delay before turning off the chip to avoid long ramp up delay. Signed-off-by:

According to the documentation, simply reading the respective MSR isn't sufficient: It should be written with zeros, cpuid(1) be executed, and then read (see arch/x86/kernel/cpu/intel.c for an example). v2: Fail probe when microcode revision cannot be determined, but is needed to check for proper operation.

The axis-mapping of lis3dev device on many (rather most) HP machines doesn't follow the standard. When each new model appears, users need to adjust again. Testing this requires the rebuild of kernel, thus it's not trivial for end-users. This patch adds a module parameter "axes" to allow a custom axis-mapping without patching and recompiling the kernel driver. User can pass the parameter such as axes=3,2,1. Also it can be changed via sysfs. Signed-off-by:

exofs_new_inode() was incrementing the inode->i_count and decrementing it in create_done(), in a bad attempt to make sure the inode will still be there when the asynchronous create_done() finally arrives. This was very stupid because iput() was not called, and if it was actually needed, it would leak the inode. However all this is not needed, because at exofs_evict_inode() we already wait for create_done() by waiting for the object_created event. Therefore remove the superfluous ref counting and just Thicken the comment at exofs_evict_inode() a bit. While at it change places that open coded wait_obj_created() to call the already available wrapper.

Export the cpu configuration topology via sysinfo. Two new lines are introduced: CPU Topology HW: 0 0 0 4 6 4 CPU Topology SW: 0 0 0 0 4 24 The HW line describes the cpu topology nesting levels when the maximum nesting level is used to get the corresponding SYSIB. The SW line describes what Linux is actually using. In this case it supports only two levels (CONFIG_SCHED_BOOK off) and therefore the hardware folded the two lower levels in the SYSIB response block. Signed-off-by:
