-This ioctl allows the user to create or modify a guest physical memory
-slot. When changing an existing slot, it may be moved in the guest
-physical memory space, or its flags may be modified. It may not be
-resized. Slots may not overlap.
-
-The flags field supports just one flag, KVM_MEM_LOG_DIRTY_PAGES, which
-instructs kvm to keep track of writes to memory within the slot. See
-the KVM_GET_DIRTY_LOG ioctl.
-
-It is recommended to use the KVM_SET_USER_MEMORY_REGION ioctl instead
-of this API, if available. This newer API allows placing guest memory
-at specified locations in the host address space, yielding better
-control and easy access.
+This ioctl is obsolete and has been removed.
