Subject: [patch 0/5] sparse-vmemmap: hotplug fixes & cleanups
Hotplug can happen at times when the memory situation is less than
perfect to allocate huge pages for the vmemmap. This series makes the
allocation try harder in patch #1. The remaining patches allow x86-64
to fall back to regular pages as a last resort before the hotplug
event fails completely. As a prerequisite to this, the arch interface
to sparse is cleaned up a little, which should also enable other
architectures to easily mix huge and regular pages in the vmemmap.
