Comment:

 The latest PJ4B errata documents from Marvell document this hardware bug,
 and suggest disabling static branch prediction. The errata docs for the
 PJ4B-B1 version (to be included in the XO-4 C1) also includes this errata.
 So I've pushed an arm-3.5 kernel hack to disable static branch prediction:
