[Michel Normand <normand@linux.vnet.ibm.com>]

as per rhbz https://bugzilla.redhat.com/show_bug.cgi?id=1125883
the mdadm is failing on ppc64 and ppc64le architectures.

super-ddf.c: In function '_set_config_size':
super-ddf.c:2849:4: error: format '%llx' expects argument of type 'long long unsigned int', but argument 6 has type '__u64' [-Werror=format=]
    pr_err("%s: %x:%x: workspace size 0x%llx too big, ignoring\n",
    ^
super-ddf.c:2855:2: error: format '%llx' expects argument of type 'long long unsigned int', but argument 6 has type '__u64' [-Werror=format=]
  dprintf("%s: %x:%x config_size %llx, DDF structure is %llx blocks\n",
  ^
cc1: all warnings being treated as errors
<builtin>: recipe for target 'super-ddf.o' failed
