powerpc/kvm: Contiguous memory allocator based hash page table allocation
Powerpc architecture uses a hash based page table mechanism for mapping virtual addresses to physical address. The architecture require this hash page table to be physically contiguous. With KVM on Powerpc currently we use early reservation mechanism for allocating guest hash page table. This implies that we need to reserve a big memory region to ensure we can create large number of guest simultaneously with KVM on Power. Another disadvantage is that the reserved memory is not available to rest of the subsystems and and that implies we limit the total available memory in the host. This patch series switch the guest hash page table allocation to use contiguous memory allocator.
