Subject: [PATCH 00/19] Input and HID updates for 3.7

Dmitry, Jiri,

Here is the tentative patchset planned for 3.7. It touches both the
Input and HID subsystems, so I decided to send it to both of you at
once. How to distribute the patches can be decided later.

The gist of the set is in-kernel tracking and latency. As I started
measuring irqsoff times, I realized we did quite poorly in that
department. Consequently, some of the patches are general and
substantial speedups which ought to make everybody happy.

Patches 1-6 rearranges the input core to send packets of events
instead of one event at a time.

Patch 7 implements this in evdev.

Patches 8-11 incorporate more duplicated code into mt core, and
implements a simple - but correct - form of tracking. Earlier variants
have either been complex, approximate or slow. This one is only about
50 lines of code and fast enough to handle ten fingers in interrupt
context.

Patches 12-15 convert bcm5974 to MT-B.

Patch 16 is janitory.

Patch 17 provides a substantial latency improvement on simple key
strokes.

Patches 18-19 are for hid-multitouch, reducing memory and simplifying
the driver.

Thanks,
Henrik
