pvops kernels >= 2.6.30 can currently only be saved and restored once. The
second attempt to save results in:
ERROR Internal error: Frame# in pfn-to-mfn frame list is not in pseudophys
ERROR Internal error: entry 0: p2m_frame_list[0] is 0xf2c2c2c2, max 0x120000
ERROR Internal error: Failed to map/save the p2m frame list
I finally narrowed it down to:

xen: split construction of p2m mfn tables from registration
Build the p2m_mfn_list_list early with the rest of the p2m table, but
register it later when the real shared_info structure is in place.
Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>
The unforeseen side-effect of this change was to cause the mfn list list to not
be rebuilt on resume. Prior to this change it would have been rebuilt via
xen_post_suspend() -> xen_setup_shared_info() -> xen_setup_mfn_list_list().
Fix by explicitly calling xen_build_mfn_list_list() from xen_post_suspend().
