my aversion to #if 0 kicks in here :(.. do we have an alternative
like using the CONFIG_ENABLE_OFF_MODE_JTAG_ETM_DEBUG or something
else?

Fair enough. I could replace it with "#if !defined(...)" as the first
thing that comes to mind. This way it will only take disabling the
config option to catch any possible regressions in between. Does this
sound reasonable?
sounds ok to me.. unless folks have ideas coz of clean_l2 label.. more comments might be useful before a rev2 of the patch..
