-What:   KVM kernel-allocated memory slots
-When:   July 2010
-Why:    Since 2.6.25, kvm supports user-allocated memory slots, which are
-        much more flexible than kernel-allocated slots.  All current userspace
-        supports the newer interface and this code can be removed with no
-        impact.

 What:   KVM paravirt mmu host support
 When:   January 2011
 Why:    The paravirt mmu host support is slower than non-paravirt mmu, both

-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+This ioctl is obsolete and has been removed.
