Ah... ok I think I see the difference here. The MXS architecture has CONFIG_HIGHMEM=n whereas Arndale has CONFIG_HIGHMEM=y. So that means on MXS all the pages will always be in low mem so I think will always be mapped into the kernel logical address space hence no problems. Not sure if it would be worth updating the driver or not, what do you think?
This is a user configurable option, it's not something that depends on the architecture (and in any case it's better not to leave people wondering why things are different when they consider consolidation).
