the following patch should do the job (sent to the maintainer as well):

This is not the correct fix since i8237 has nothing to do with SMP.
the problem lies somewhere in the include dependancy.

asm-i386/mach-xen/asm/system.h <- included by spinlock.h <- include by dma.h
need some linux/smp.h definition
I failed to see what is the good fix right now ..

you can compile a SMP kernel for the moment (and add CONFIG_SMP_ALT if
you are really worried of the performance)
