In v9 I currently have this and the ARM trace event from this series
both wrapped in an
ifdef verifying that CONFIG_RAS is enabled. This resolves the kbuild

think I
should use the ifdef or use these *_enabled() functions?
I believe you need both. The *_enabled() functions wont prevent build
errors. But since tracing is seldom enabled (usually only when you want
to see what's happening), the *_enabled() functions optimize the code
to not perform tasks that are only needed when tracing is enabled. When
I say "enabled" I mean actively tracing, as supposed to being just
enabled in the kernel.

Got it, I will add both!
Thanks,
