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.
