[PATCH 0/4] powerpc: Memory hotplug cleanups

From: David Gibson
Date: Wed Jan 27 2016 - 21:40:19 EST


These are some fairly straightforward cleanups to the memory hotplug
paths on powerpc. Mostly it deals with more graceful handling of
failure cases.

This series is a soft prerequisite for my patches for HPT resizing on
pseries.

arch/powerpc: Clean up error handling for htab_remove_mapping
arch/powerpc: Handle removing maybe-present bolted HPTEs
