Content for the 8bit device threaded interrupt handlers. Depending on the interrupt line and chip configuration, either click or wakeup / freefall handler is called. In case of click, BTN_ event is sent via input device. In case of wakeup or freefall, input device ABS_ events are updated immediatelly. It is still possible to configure interrupt line 1 for fast freefall detection and use the second line either for click or threshold based interrupts. Or both lines can be used for click / threshold interrupts. Polled input device can be set to stopped state and still get coordinate updates via input device using interrupt based method. Polled mode and interrupt mode can also be used parallel. BTN_ events are remapped based on existing axis remapping information. Signed-off-by:

Original lis3 driver didn't provide interrupt handler(s) for click or threshold event handling. This patch adds threaded handlers for one or two interrupt lines for 8 bit device. Actual content for interrupt handling is provided in the separate patch. Signed-off-by:

8 bit device has two wakeup / free fall units. It was not possible to configure the second unit. This patch introduces configuration entry to the platform data and also corresponding changes to the 8 bit setup function. High pass filters were enabled by default. Patch introduces configuration option for high pass filter cut off frequency and also possibility to disable or enable the filter via platform data. Since the control is a new one and default state was filter enabled, new option is used to disable the filter. This way old platform data is still compatible with the change. Signed-off-by:

drivers/char/hangcheck-timer.c is doubly broken. When the overflown value of TIMER_FREQ is abnormally low, it spams the syslog with KERN_CRIT messages "Hangcheck: hangcheck value past margin!" But whether it happens or not depends on HZ and lpj in a complex way. People have hit it occasionally as far as google search can tell. First, the following line overflows unsigned long: # define TIMER_FREQ (HZ*loops_per_jiffy) Second, and more importantly, loops_per_jiffy has little to do with the con= version from the the time scale of get_cycles() (aka rdtsc) to the time scale of jiffies. The attached patch resolves both of the problems. Acked-by:

Currently, the menu governor uses the (corrected) next timer as key item for predicting the idle duration. It turns out that there are specific cases where this breaks down: There are cases where we have a very repetitive pattern of idle durations, where the idle period is pretty much the same, for reasons completely unrelated to the next timer event. Examples of such repeating patterns are network loads with irq mitigation, the mouse moving but in theory also the wifi beacons. This patch adds a relatively simple detector for such repeating patterns, where the standard deviation of the last 8 idle periods is compared to a threshold. With this extra predictor in place, measurements show that the DECAY factor can now be increased (the decaying average will now decay slower) to get an even more stable result.

Add a per-node sysfs file called compact. When the file is written to, each zone in that node is compacted. The intention that this would be used by something like a job scheduler in a batch system before a job starts so that the job can allocate the maximum number of hugepages without significant start-up cost.

This reverts commit 03ceedea , since it breaks resume from suspend-to-ram on Rafael's Acer Ferrari One. NetworkManager thinks everything is ok, but it can't connect to the AP to get an IP address after the resume. In fact, it even breaks resume for non-ath9k chipsets: reverting it also fixes Rafael's Toshiba Protege R500 with the iwlagn driver. As Johannes says: "Indeed, this patch needs to be reverted. That mac80211 change is wrong and completely unnecessary." Reported-and-requested-by:
