I don't think it would be the best to mention specific hardware platforms in the commit text. If I saw this patch listing specific hardware platforms I would have made the wrong decision (I would look at the list and decide that I am not running on those platforms so I don't need this patch). The problem could happen on any hardware platform. It just depends on how the memory map of the platform is configured. Hence, I re-worded the commit text to make it clear that this will happen when you have memory starting at 0x0. If I list out specific hardware platforms it would be only a sample (I do not know all hardware platforms and their memory maps). However, having said that there are products already shipping with physical address starting at 0.
