Subject[PATCH RT 2/7] timer: Invoke timer_start_debug() where it makes sense
Date
From: Thomas Gleixner <tglx@linutronix.de>

The timer start debug function is called before the proper timer base is
set. As a consequence the trace data contains the stale CPU and flags
values.

Call the debug function after setting the new base and flags.
