[PATCH v1 01/47] x86: mtrr: annotate mtrr_type_lookup() is only implemented on generic_mtrr_ops

[Luis R. Rodriguez]

From: "Luis R. Rodriguez" <mcgrof@xxxxxxxx>

There area few users of mtrr_type_lookup(), including PAT.
Note that PAT can be in theory enabled without MTRR fully
kicking in, such is the case with Xen.
