-Subject: [PATCH] Fix: update timer instrumentation on 4.16 and 4.14-rt

-  commit 63e2ed3659752a4850e0ef3a07f809988fcd74a4

-    tracing/hrtimer: Print the hrtimer mode in the 'hrtimer_start' tracepoint
-
-    The 'hrtimer_start' tracepoint lacks the mode information. The mode is
-    important because consecutive starts can switch from ABS to REL or from
-    PINNED to non PINNED.
-
-    Append the mode field.
