[Xen-ia64-devel] [IA64] Kexec: xen_foreign_p2m_expose() needs CONFIG_XEN_IA64_EXPOSE_P2M

[Simon Horman <horms@xxxxxxxxxxxx>]

ia64/linux-2.6.18-xen.hg 197:e1466633683c "[IA64] Foreign p2m: linux side"
causes a build regression when the config does not set
CONFIG_XEN_IA64_EXPOSE_P2M.

arch/ia64/xen/built-in.o: In function 
`xencomm_privcmd_ia64_dom0vp_op':arch/ia64/xen/xcom_privcmd.c:736: undefined 
reference to `xen_foreign_p2m_expose'
make: *** [.tmp_vmlinux1] Error 1

This patch should resolve the problem.
