Public bug reported: When commit 83e3c48729d9ebb7af5a31a504f3fd6aff0348c4 ("mm/sparsemem: Allocate mem_section at runtime for CONFIG_SPARSEMEM_EXTREME=y") was backported, it broke the exporting of mem_section on vmcoreinfo.
makedumpfile will fail to dump in that case. Backporting a kernel fix will make it work again, but that means that some kernel versions won't be dumpable. A solution for makedumpfile should be done as well.
