[Xen-devel] [PATCH v4 16/16] libxl/arm: Add the size of ACPI tables to maxmem

[Shannon Zhao <zhaoshenglong@xxxxxxxxxx>]

From: Shannon Zhao <shannon.zhao@xxxxxxxxxx>

While it defines the maximum size of guest ACPI tables in guest
memory layout, here it adds the size to set the target maxmem
to avoid providing less available memory for guest.
