With CONFIG_SPARSEMEM_EXTREME enabled, __section_nr() which converts mem_section to section_nr could be costly since it iterates all section roots to check if the given mem_section is in its range. On the other hand, __nr_to_section() which converts section_nr to mem_section can be done in O(1). Let's pass section_nr instead of mem_section ptr to find_memory_block() in order to reduce needless iterations. Signed-off-by: Ohhoon Kwon <ohoono.kwon@xxxxxxxxxxx>
