Currently the number of vcpus on arm64 with GICv3 is limited up to 8 due to the fixed size of redistributor mmio region. Increasing the size makes the number expand to 16 because of AFF0 restriction on GICv3. To create a guest up to 128 vCPUs, which is the maxium number that GIC-500 can support, this patchset uses the AFF1 information to create a mapping relation between vCPUID and vMPIDR and deals with the related issues. These patches are written based upon Julien's "GICv2 on GICv3" series. Changes from V1: * Use the way that expanding the GICR address space to support up to 128 redistributor in guest memory layout rather than use the dynamic allocation. * Add support to include AFF1 information in vMPIDR/logical CPUID.
