tools/libxc/xc_private.c:265
  #ifndef __ia64__
  int xc_get_pfn_list(int xc_handle,
                    uint32_t domid,
                    xen_pfn_t *pfn_buf,
                    unsigned long max_pfns)

the patch would change this "libxc private" interface to

  int xc_get_pfn_list(int xc_handle,
                    uint32_t domid,
                    xen_pfn_t *pfn_buf,
+                   xen_pfn_t start_pfn,
                    unsigned long max_pfns)

use the start_pfn member of struct xen_domctl_getmemlist
Fix all callers and change xen to pay attention to it, I think I have  
the x86-xen patch.
