I thought we were going to enable these in rawhide since the e1000
EEPROM problem was fixed:
CONFIG_FUNCTION_TRACER (was CONFIG_FTRACE)
CONFIG_DYNAMIC_FTRACE
Last I knew this still uses -pg and implies -fno-omit-frame-pointer.
This probably kills performance somewhat, and more importantly during a
rawhide debug-kernel phase, might change the corners of compiler behavior
that we're checking vs what we'd want in a production kernel.
