Deal with address offsets. Address lookup is now:

Browse Source

	Deal with address offsets. Address lookup is now:

	- First convert the address to an offset into the file
	- Then convert to an offset into the text segment
	- Then add the load address of the text segment (found in the
	debug binary)
	- Then finally lookup the result in the symbol table.

	* elfparser.c (elf_parser_get_text_offset): New function

	* elfparser.c (elf_parser_lookup_symbol): Treat addresses as
	offsets into the text segment.

	* binfile.c (bin_file_new): Store the offset of the text section
	of the actual binary (not the debug one)

	(bin_file_lookup_symbol): Subtract text_offset before passing
	address to elf parser.

	* module/sysprof-module.c: Remove include of linux/config.h
