Hi Rusty,

yes, this looks like better approach. I will respin that patch.

I see two options how to do this -- either I can make 'value' input 
parameter too, so that find_symbol_in_section() could perform lookup 
either according to address or according to name (whatever is specified in 
the passed struct find_symbol_arg), or I can do a completely new lookup 
function for address-wise lookups. What would you prefer? I don't have any 
strong preference either way.

Thanks,
