Hi Rahul,

Please give the necessary justification for inclusion in 4.17:
- severity of the bug fixed
- probability and impact of potential issues that the patch could add.

thanks

The severity of the bug is high as without this fixed system with ACPI support will fail to boot.

As we are not supporting the static event channel for ACPI, it is okay to move
alloc_static_evtchn() under acpi_disabled check.

I agree on that, dom0 boot from ACPI on Arm is what we currently supported.
So I think we need to fix the current issue for 4.17.

Besides the bugfix patch, the other patch in this series is a pure doc change
so it should be safe.

I think we still need Arm maintainers' R-b or ack for this series, and as long as
This series is properly reviewed:
