[PATCH V2 0/2] hrtimer: Iterate only over active clock-bases

[Viresh Kumar]

Hi,

'active_bases' indicates which clock-base have active timers. While it
is updated (almost) correctly, it is hardly used.

And so this is an attempt to improve the code that iterates over all
clock-bases.

The first patch fixes a issue that will result in a bug after the second commit,
and the second commit creates a macro for_each_active_base() and uses it at
multiple places.

V1->V2:
- Dropped ffs() and wrote own routine __next_bit().

Viresh Kumar (2):
  hrtimer: update '->active_bases' before calling
    hrtimer_force_reprogram()
  hrtimer: create for_each_active_base() to iterate over active
    clock-bases
