The patch titled Subject: mm/sparse: more checks on mem_section number has been removed from the -mm tree. Its filename was mm-sparse-more-check-on-mem_section-number.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Gavin Shan <shangw@xxxxxxxxxxxxxxxxxx> Subject: mm/sparse: more checks on mem_section number __section_nr() was implemented to retrieve the corresponding memory section number according to its descriptor. It's possible that the specified memory section descriptor doesn't exist in the global array. So add more checking on that and report an error for a wrong case.
