It's turned out to be the recent commint in the upstream:

  commit 621a0d5207c18012cb39932f2d9830a11a6cb03d
  Author: Peter Zijlstra <a.p.zijlstra@...llo.nl>
  Date:   Wed Nov 12 09:36:35 2008 +0100

    hrtimer: clean up unused callback modes

    Impact: cleanup

    git grep HRTIMER_CB_IRQSAFE revealed half the callback modes are actually
    unused.

This hits on snd-pcsp driver on linux-next, since it was switched to
use this dropped flag.  Now we get a build error.

Can this commit be reverted?


thanks,

Takashi
