Subject: [for-4.7 5/5] xen/arm: acpi: Print more error messages in acpi_map_gic_cpu_interface

Message-ID: <1460026796-10899-6-git-send-email-julien.grall@arm.com> (raw)
In-Reply-To: <1460026796-10899-1-git-send-email-julien.grall@arm.com>
It's helpful to spot any error without having to modify the hypervisor
code.
