Use recursive grep or similar to find uses of those functions in Xen. Find
out what DOMCTL command they are associated with, search for that in similar
way in tools/libxc directory, search for uses of the libxc interface
function elsewhere in tools/, and so on.

You'll find mem_sharing_share_page will take you from Xen to tools/libxc to
tools/memshr to tools/blktap2.

find . -name '*.c' | xargs grep -n <word_to_search_for>
