e820_search_gap() is just used locally now and the 'start_addr' and 'end_addr' parameters are fixed values. Also, 'gapstart' is not checked in this function anymore. So make the function static and remove those unused variables. Signed-off-by: Wei Yang <richard.weiyang@gmail.com> Acked-by: Yinghai Lu <yinghai@kernel.org> Cc: H.
