[Qemu-ppc] [RFC PATCH v4 4/5] spapr: Make hash table size a factor of ma

Subject: [Qemu-ppc] [RFC PATCH v4 4/5] spapr: Make hash table size a factor of maxram_size
Date: Fri, 19 Jun 2015 15:47:56 +0530

The hash table size is dependent on ram_size, but since with hotplug
the memory can grow till maxram_size. Hence make hash table size dependent
on maxram_size.

This allows to hotplug huge amounts of memory to the guest.
