I tried to build a Linux kernel from current git sources without specifying 
any form of Xen.  I got these three undefined symbols:

xen_register_gsi
xen_teardown_msi_dev
xen_setup_msi_irqs

I defined them as dummy functions in arch/x86/include/asm/xen/pci.h for the 
case where CONFIG_XEN is not set, and got a working kernel.  They're also 
defined as dummy functions higher in the file under #else clauses for other 
config variables.  I assume we don't want the dummy functions defined multiple 
times, but I'm not sure the cleanest solution.
