Subject: [GIT PULL] nohz patches for 3.12 preview v3

Hi,

So none of the patches from the previous v2 posting have changed.
I've just added two more in order to fix build crashes reported
by Wu Fengguang:

      hardirq: Split preempt count mask definitions
      m68k: hardirq_count() only need preempt_mask.h

If no comment arise, I'll send a pull request to Ingo in a few days.

Thanks.
