As you are effectively adding a new clocksource driver here, please move the
code to drivers/clocksource and send the patch to the respective maintainers
(added to Cc here), splitting it out from the rest of the patch.
You should also describe why your platform doesn't just use the normal
architected timer interface.
> +TIMER_ACPI_DECLARE(hyperv, ACPI_SIG_GTDT, hyperv_init);
This looks like it registers a driver for the same device as the normal
arch timer. Won't that clash?
