Xenial does not have 83e3c48729d9ebb7af5a31a504f3fd6aff0348c4. Though,
linux-hwe 4.13 has been shipped for Xenial. So, on the kernel side,
there is nothing to fix on our 4.4 kernels, but on the makedumpfile
side, that still needs to be fixed if we want to have some of those
kernels dumpable.
** Description changed:
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.
