I'm not aware of any problems like that. There used to be some problems with FTRACE and some userspace tools, but it was mostly about symbol de-mangling, so in other words it doesn't break anything else.
I've just spoken to Will Deacon and he has similar opinion, so yes - I'd say let's enable all of this on all platforms.
Now, I had a look at OMAP flavour configuration and all the relevant options are already enabled there. Note that the "CONFIG_ENABLE_DEFAULT_TRACERS" is not available there, because other tracers are enabled and they select the "CONFIG_GENERIC_TRACER" option (that's the one we really care about ;-). It's all described in commit 5e0a093910876882f91f1d4b8a1635a099e6c7ba "tracing: fix config options to not show when automatically selected" in the main line.
