[ARM] do_bad_area() always takes current and current->active_mm
Since do_bad_area() always takes the currently active task and (supposed to) take the currently active MM, there's no point passing them to this function. Instead, obtain references to them inside do_bad_area(). Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
