Hi,

   Changeset 8694 introduced dummy __gpfn_to_mfn and __mfn_to_gpfn into
the common xen/include/shadow.h header.  Unfortunately ia64 uses these
functions and has it's own definition for them.  The dummy versions are
overriding the real version in xen/common/grant_table.c, which causes a
hang somewhere between the startup of the networking code and mounting
the root fs on an ia64 domU domain.  Proposed patch below.  Thanks,

        Alex
