XEN0 kernel with options MULTIPROCESSOR

["Florent Parent" <florent.parent%gmail.com@localhost>]

Hello,

Is it possible to have a domain0 kernel with multiprocessor enabled
(Xen2)? I basically started with XEN0 kernel config and added the
following lines:

options         MULTIPROCESSOR
options         COM_MPLOCK      # com MP locking; REQUIRED on MP i386
options         MPBIOS          # configure CPUs and APICs using MPBIOS

Kernel compilation generates the following error. It looks like
something else is missing in the kernel configuration. Any pointers
appreciated.
