There is no need for those functions/variables to be visible. Make them static and also fix the compile warnings of this sort: drivers/xen/<some file>.c: warning: symbol '<blah>' was not declared. Should it be static? Some of them just require including the header file that declares the functions. Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
