2012-04-03Input: sentelic - filter taps in absolute modeOskari Saarenmaa
Taps in absolute positioning single-finger mode are currently reported as physical clicks by the driver. This should be handled by userspace, not the kernel. When a tap occurs, the FSP_PB0_LBTN bit is set, but the FSP_PB0_PHY_BTN is not. We use this to filter out physical clicks from taps.

2012-04-03drm: Validate requested virtual size against allocated fb sizeChris Wilson
mplayer -vo fbdev tries to create a screen that is twice as tall as the allocated framebuffer for "doublebuffering". By default, and all in-tree users, only sufficient memory is allocated and mapped to satisfy the smallest framebuffer and the virtual size is no larger than the actual. For these users, we should therefore reject any userspace request to create a screen that requires a buffer larger than the framebuffer originally allocated.

2012-04-03md/raid1,raid10: don't compare excess byte during consistency check.NeilBrown
When comparing two pages read from different legs of a mirror, only compare the bytes that were read, not the whole page. In most cases we read a whole page, but in some cases with bad blocks or odd sizes devices we might read fewer than that. This bug has been present "forever" but at worst it might cause a report of two many mismatches and generate a little bit extra resync IO, so there is no need to back-port to -stable kernels.

Because the judgement in function analyse_stripe(): if (do_recovery || sh->sector >= conf->mddev->recovery_cp) s->syncing = 1; else s->replacing = 1; When check or repair,the recovery_cp == MaxSectore,so syncing equal zero not one.

2012-04-03APM: fix deadlock in APM_IOC_SUSPEND ioctlNeilBrown
I found the Xorg server on my ARM device stuck in the 'msleep()' loop in apm_ioctl. I suspect it had attempted suspend immediately after resuming and lost a race. During that msleep(10);, a new suspend cycle must have started and changed ->suspend_state to SUSPEND_PENDING, so it was never seen to be SUSPEND_DONE and the loop could never exited. It would have moved on to SUSPEND_ACKTO but never been able to reach SUSPEND_DONE. So change the loop to only run while SUSPEND_ACKED rather than until SUSPEND_DONE. This is much safer.

The code tries various methods for retreiving the BIOS data. However it doesn't clear the bios->data pointer between the iterations. In some cases, the shadow() method will fail and not update bios->data at all, which will cause us to "score" the old data and incorrectly attribute that score to the new method. This can cause double frees later when disposing of the unused data. Additionally, we were not freeing the data for methods that fail the score test (we only freed when a "best" is superseeded, not when the new method has a lower score than the exising "best").
