This allows to modify up to eight bytes in a row instead of only four. For function tracer enabling and disabling this reduces the time needed to modify the text sections by 50%, since for each mcount call site six bytes need to be changed. Also remove the EXTABLE entries, since calls to this function are not supposed to fail. Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky --- Reading git-diff-tree failed
