[Xen-devel] [PATCH v12 10/14] xsm/flask: avoid spurious error messages when mapping I/O-memory

[Arianna Avanzini <avanzini.arianna@xxxxxxxxx>]

Currently, FLASK only handles the memory_mapping hypercall for the
x86 architecture. In case the architecture is ARM, an error message
will be printed regardless of how XSM has been configured. This
commit lets the memory_mapping case be handled also for architectures
other than x86.
