KVM: Add coalesced MMIO support (powerpc part)
This patch enables coalesced MMIO for powerpc architecture. It defines KVM_MMIO_PAGE_OFFSET and KVM_CAP_COALESCED_MMIO. It enables the compilation of coalesced_mmio.c. Signed-off-by: Laurent Vivier <Laurent.Vivier@bull.net> Signed-off-by: Avi Kivity <avi@qumranet.com>
