[PATCH 0/2] powerpc/pseries: Implemented indexed-count hotplug memory management

Indexed-count memory management allows addition and removal of contiguous
lmb blocks to be added and removed with a single command. When compared
to the series of calls previously required to manage contiguous blocks,
indexed-count decreases command frequency and complexity, consequently
preventing buffer overflow.
