Description:
 The xenmem_add_to_physmap_one function in arch/arm/mm.c in Xen 4.5.x,
 4.4.x, and earlier does not limit the number of printk console messages
 when reporting a failure to retrieve a reference on a foreign page, which
 allows remote domains to cause a denial of service by leveraging
 permissions to map the memory of a foreign guest.
