Subject: [PATCH v6 00/10] arm64: Add support for KVM with ACPI

[+ Thomas, Jason]

Do you have any objection against this going through the KVM tree? The
dependencies are rather intricate, and Daniel gave us his green light
already for the clocksource part.

If you'd rather maintain the usual flow, please let us know and we'll
deal with it.

Thanks,

	M.
