[Xen-devel] [PATCH v4 04/10] acpi: Don't do traditional BIOS table scan for ARM64

[Shannon Zhao <zhaoshenglong@xxxxxxxxxx>]

From: Shannon Zhao <shannon.zhao@xxxxxxxxxx>

With the addition of ARM64 that does not have a traditional BIOS to
scan, stub out acpi_find_root_pointer to do nothing for ARM.
