Sure.
Our source tree for Maverick encompasses all our major supported
platforms in one git branch. Thus, we have one common config file and a
bunch of arch and flavour (generic, server, virtual, pae) specific
config files. One note about the common configs: if a config option
would not exist because an option in a specific config file is set a
certain way, then you can ignore it for that specific arch/flavour. For
example, the common config has CONFIG_DYNAMIC_FTRACE=y, but the armel
config has "CONFIG_FUNCTION_TRACER is not set" so the former would not
have any affect on armel builds.
You can find the source branch at

Some of the above is not FTRACE. I also snipped the matches in
config.common.ports because they are slightly different due to what the
ports architectures support, but they should be pretty similar.
Please let me know if anything stands out at you as incorrect.
Thanks,
