David Dai b7e72de084 aarch64: Use cpu_capacity to determine clustering instead 
Some systems do not populate cpu-map information and
use other ways of grouping CPUs in a frequency/topology
domain instead. Use normalized cpu_capacity information
to determine clustering instead.

crosvm - The ChromeOS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the ChromeOS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on ChromeOS devices.
