IA64: SPARSEMEM_VMEMMAP 16K page size support
Equip IA64 sparsemem with a virtual memmap. This is similar to the existing
CONFIG_VIRTUAL_MEM_MAP functionality for DISCONTIGMEM. It uses a PAGE_SIZE
mapping.
This is provided as a minimally intrusive solution. We split the 128TB
VMALLOC area into two 64TB areas and use one for the virtual memmap.
This should replace CONFIG_VIRTUAL_MEM_MAP long term.
