[RFC PATCH 1/5] linux-headers: [kvm, arm64] add the necessary definitions to match host kernel

[Miguel Luis <miguel.luis@oracle.com>]

From: Haibo Xu <haibo.xu@linaro.org>

linux-headers define host properties needed for the VMM to interact with
KVM, so let's include them *while* they're not available yet on linux
upstream since aarch64 nested virtualization is still a work in
progress.
