[PATCH 2/5] xen: remove unused function warnings

[Steven Rostedt]

The compiler is complaining that there are unused static functions
in the Xen code. Looking into this, it seems that they are used
but only within #if statements.

This patch matches the functions with the #if statements that they
are referenced by.
