[patch V2 14/20] timer: Move __run_timers() function

[Thomas Gleixner <tglx@linutronix.de>]

[-- Attachment #1: timer_Move___run_timers_function.patch --]
[-- Type: text/plain, Size: 2315 bytes --]

From: Anna-Maria Gleixner <anna-maria@linutronix.de>

Move __run_timers() below __next_timer_interrupt() and next_pending_bucket()
in preparation for __run_timers() NOHZ optimization.

No functional change.
