Subject: [PATCH V2 15/36] hrtimer: don't emulate notifier call to initialize timer base
In hrtimers_init() we need to call init_hrtimers_cpu() for boot cpu. For this,
currently we are emulating a call to hotplug notifier. Probably this was done
initially to get rid of code redundancy. But this sequence always called a
single routine, i.e. init_hrtimers_cpu(), and so calling that routine directly
would be better. This would get rid of emulating a notifier call, few typecasts
and the extra steps we are doing in notifier callback.
So, this patch calls init_hrtimers_cpu() directly from hrtimers_init().
