Hello,

This patch series allows KVM to work with ACPI on ARM64.

Currently, the firmware tables are parsed by the the virtual timer and virtual
GIC code in order to configure them correctly.

However the parsing of these tables is already done in the GIC and arch timer
drivers. This patch series introduces new helpers to retrieve the information
from the different drivers in order to avoid duplication of the parsing code.

To make the merge easier via the different trees, each patch modifies a single
subsystem. The suggested plan to merge the series is divided in 3 steps:

1) Patches #1-#2 are merged via the clocksource tree
Patches #2-#6 are merged via the irqchip tree
2) Patches #7-#8 are merge via the KVM tree
3) Patch #9 is merged via the clocksource tree.


I'm not a clocksource or irqchip expert, and far from an ACPI expert,
but this series overall looks good to me now.

I guess we'll need to wait until the patches are in the clocksource and
irqchip trees, and then merge that into the kvmarm tree, and apply patch
7 and 8 on top, or is there a simpler way to do this?

The simpler way would be carrying all the patches in a single tree (such as the KVM ARM tree). If we are going this way, I would need the ack from all the maintainers in this case.
