[PATCH] mm/sparse: use __nr_to_section(section_nr) to get mem_section

__pfn_to_section is defined as __nr_to_section(pfn_to_section_nr(pfn)). Since we already get section_nr, it is not necessary to get mem_section from start_pfn. By doing so, we reduce one redundant operation. Signed-off-by: Wei Yang --- mm/sparse.c | 2 +- 1 file changed, 1 insertion(+), 1 delet
