2010-05-25fb_defio: fix for non-dirty ptesAlbert Herranz
Fix a problem observed while using fb_defio with a short delay on a PowerPC platform. It is possible that page_mkclean() is invoked in the deferred io work function _before_ a PTE has been marked dirty. In this case, the page is removed from the defio pagelist but page_mkclean() does not write-protect the page again. The end result is that defio ignores all subsequent writes to the page and the corresponding portions of the framebuffer never get updated. The fix consists in keeping track of the pages with non-dirty PTEs, re-checking them again on the next deferred io work iteration. Note that those pages are not passed to the defio callback as they are not written by userspace yet.

2010-05-25fbdev: da8xx/omap-l1xx: implement double bufferingMartin Ambrose
This work includes the following: - Implement handler for FBIO_WAITFORVSYNC ioctl. - Allocate the data and palette buffers separately. A consequence of this is that the palette and data loading is now done in different phases. And that the LCD must be disabled temporarily after the palette is loaded but this will only happen once after init and each time the palette is changed. I think this is OK. - Allocate two (ping and pong) framebuffers from memory. - Add pan_display handler which toggles the LCDC DMA registers between the ping and pong buffers.

2010-05-25rtc-cmos: do dev_set_drvdata() earlier in the initializationDan Carpenter
The bug is an oops when dev_get_drvdata() returned null in cmos_update_irq_enable(). The call tree looks like this: rtc_dev_ioctl() => rtc_update_irq_enable() => cmos_update_irq_enable() It's caused by a race condition in the module initialization. It is rtc_device_register() which makes the ioctl operations live so I moved the call to dev_set_drvdata() before the call to rtc_device_register().

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.

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.

2010-05-25hangcheck-timer: fix x86_32 bugsYury Polyanskiy
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.

2010-05-25cpuidle: add a repeating pattern detector to the menu governorArjan van de Ven
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.
