[PATCH 0/4] powerpc/mm: Cleanups to hotplug memory path

[David Gibson]

The cleanups to the (guest side) memory hotplug paths came up in the
context of allowing hash page table resizing for PAPR guests.
However, they stand on their own and can improve reporting of several
error conditions that could already happen.

Please apply.
