Bug description:
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.
Cascardo.
