  commit ae763e4224304983a1cde2fbb3d6e0c4d60b2688
  Author: Dario Faggioli <dario.faggioli@citrix.com>
  Date:   Tue Sep 10 19:54:20 2013 +0200
  
      tools/misc: introduce xen-mfndump.
      
      A little development and debugging tool, useful when looking
      for information about MFN to PFN mappings, MFN/PFN mappings
      in a guest''s PTEs, etc.
      
      This is what it can do as of now:
      
      $ /usr/sbin/xen-mfndump
      Usage: xen-mfndump <command> [args]
      Commands:
        help                      show this help
        dump-m2p                  show M2P
        dump-p2m    <domid>       show P2M of <domid>
        dump-ptes   <domid> <mfn> show the PTEs in <mfn>
        lookup-pte  <domid> <mfn> find the PTE mapping <mfn>
        memcmp-mfns <domid1> <mfn1> <domid2> <mfn2>
                                  (str)compare content of <mfn1> &
<mfn2>

Looking at the logs, this is correct:

cc1: warnings being treated as errors
xen-mfndump.c: In function ''dump_ptes_func'':
xen-mfndump.c:236: error: format ''%lx'' expects type
''long unsigned int'', but argument 3 has type
''uint64_t''
xen-mfndump.c: In function ''lookup_pte_func'':
xen-mfndump.c:305: error: format ''%lx'' expects type
''long unsigned int'', but argument 5 has type
''uint64_t''
make[3]: *** [xen-mfndump.o] Error 1

You need to make the types and the printf formats consistent, perhaps
by use of PRIx64 et al.

Yes, sorry, I checked staging and not remotes/origin/staging for the
fix...
