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This ioctl is obsolete and has been removed.
