Andrew,

I'm fine with this series wrt to fixing Linux, however:

I think we're losing knowledge here.  *We* know that attempting to
enable transaction offload on A0 SoCs is bad news.  Other OS's would now
need to dig through the Linux kernel code for clues as to what's
happening.

Perhaps we should retain the info in the form of a note at the bottom of
this file?

thx,

Jason.
