[PATCH] xen: use header for EXPORT_SYMBOL_GPL

From: Randy Dunlap <redacted>

mmu.c needs to #include module.h to prevent these warnings:

arch/x86/xen/mmu.c:239: warning: data definition has no type or storage class
arch/x86/xen/mmu.c:239: warning: type defaults to 'int' in declaration of 'EXPORT_SYMBOL_GPL'
arch/x86/xen/mmu.c:239: warning: parameter names (without types) in function declaration
