      Input: apanel - convert to new i2c binding · 1561bfe5
      由 Jean Delvare 提交于 
      Convert the apanel driver to the new i2c device driver binding model,
as the legacy model is going away soon. In the new model, the apanel
driver is no longer scanning all the i2c adapters, instead the
relevant bus driver (i2c-i801) is instantiating the device as needed.

One side benefit is that the apanel driver will now load automatically
on all systems where it is needed.

      hrtimer: removing all ur callback modes · ca109491
      由 Peter Zijlstra 提交于 
      Impact: cleanup, move all hrtimer processing into hardirq context

This is an attempt at removing some of the hrtimer complexity by
reducing the number of callback modes to 1.

This means that all hrtimer callback functions will be ran from HARD-irq
context.

I went through all the 30 odd hrtimer callback functions in the kernel
and saw only one that I'm not quite sure of, which is the one in
net/can/bcm.c - hence I'm CC-ing the folks responsible for that code.

Furthermore, the hrtimer core now calls callbacks directly with IRQs
disabled in case you try to enqueue an expired timer. If this timer is a
periodic timer (which should use hrtimer_forward() to advance its time)
then it might be possible to end up in an inf. recursive loop due to the
fact that hrtimer_forward() doesn't round up to the next timer
granularity, and therefore keeps on calling the callback - obviously
this needs a fix.

Aside from that, this seems to compile and actually boot on my dual core
test box - although I'm sure there are some bugs in, me not hitting any
makes me certain :-)

      Input: replace spin_lock_bh with spin_lock_irqsave in ml_ff_playback · 8442c87d
      由 Arjan van de Ven 提交于 
      ml_ff_playback() uses spin_(un)lock_bh. However this function is
called with interrupts disabled from erase_effect() in
drivers/input/ff-core.c:196.

This is not permitted, and will result in a WARN_ON in the bottom
half handling code. This patch changes this function to just use
spin_lock_irqsave() instead, solving the problem and simplifying
the locking logic.

This was reported as entry #106559 in kerneloops.org
