[Xen-devel] [PATCH 01/34] xen: clang: Disable initializer-overrides warning

The commit 819c084 "x86/MTRR: optionally print boot time state" introduces use
of the pattern of initializing an array with a range-based default entry.
On clang it results as a compilation failure:
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] = "?",
