This patch is breaking compilation with clang 3.0:

generic.c:95:32: error: initializer overrides prior initialization of this 
subobject [-Werror,-Winitializer-overrides]
                [MTRR_TYPE_UNCACHABLE]     = "uncachable",
                                             ^~~~~~~~~~~~
generic.c:94:32: note: previous initialization is here
                [0 ... MTRR_NUM_TYPES - 1] = "?",
                                             ^~~

Do you mind if I send a patch to replace by something like:
        [2] = "?"
        [3] = "?"
