So how about using macro names that actually show the purpose, instead of 
importing all the crappy, historic, essentially randomly chosen debug symbol macro 
names from the binutils and older kernels?

Something sane, like:

	SYM__FUNCTION_START
	SYM__FUNCTION_END

	SYM__DATA_START
	SYM__DATA_END

... and extend that macro namespace with any other variants we might need.

We can still keep the old macro names (for a short while) to ease the transition, 
but for heaven's sake, if we do "cleanups" before complicating the code let's make 
sure the result is actually readable!

Agreed?

Thanks,

	Ingo
