Thank you for your advice.
I attached the patch. The cause is as follows:

1028:6f7bda25a4de includes xen-unstable 21568:05bfc5a472b which
moved struct xenctl_cpumap from domctl.h to xen.h.
However, xcom_privcmd.c includes xen.h without __XEN__ or
__XEN_TOOLS__, so struct xenctl_cpumap is invisible from
xcom_privcmd.c.

This patch fixes by defining __XEN_TOOLS__ at the top of xcom_privcmd.c.
But this causes a warning:

In file included from /linux-2.6.18-xen.hg/include/xen/interface/xen.h:30,
                 from /linux-2.6.18-xen.hg/include/xen/interface/arch-ia64.h:26,
