I don't seem to find xen/memshr, only tools/memshr -- that's the tool
for manipulating memory sharing. You might want to look into hypervsior
code arch/x86/mm/mem_sharing.c.
Note that memory sharing is not actively maintained so you might
encounter all sorts of problems and on your own to solve them.
