commit 647fe16b46999258ce1aec41f4bdeabb4f0cc8e7
Author: Steven Rostedt <rostedt@goodmis.org>
Date: Mon, 21 Jul 2025 16:40:56 +0000
As the trace event powernv_throttle is only used by the powernv code, move
it to a separate include file and have that code directly enable it.
Trace events can take up around 5K of memory when they are defined
regardless if they are used or not. It wastes memory to have them defined
in configurations where the tracepoint is not used.
