Initial ACPI support for ARM64 has been accepted into Linux kernel recently. Now it is a good time to re-visit ACPI support for KVM. This patchset enables ACPI for both arch_timer and vGIC by probing related ACPI tables and does necessary initialization. Note that Alexander Spyridaki submitted similar patches before. Some of his ideas were borrowed in this patchset, but with substancial changes. In addition we extend support for both GICv2 and GICv3. This patchset would work better on top of recent GIC/IRQCHIP patches by Hanjun Guo, who added support for gic_version in ACPI struct of GIC distributor (search "ACPICA: Introduce GIC version for arm based system"). This patchset can be applied cleanly on top of Linx 4.1-rc1.
