+What: KVM memory aliases support
+When: July 2010
+Why: Memory aliasing support is used for speeding up guest vga access
+ through the vga windows.
+
+ Modern userspace no longer uses this feature, so it's just bitrotted
+ code and can be removed with no impact.

+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
+ on newer and older hardware. It is already not exposed to the guest,
+ and kept only for live migration purposes.
