Hello Greg,
       
        I did the following compilation tests:
       
        -sh/allyesconfig/cross-compile: no longer tries to compile ion with this
patch.
(MMU is only selected on !CPU_SH2 sub-type)

        -sh/SH-x3 subtype/cross-compile (->mmu on): compilation ok

        -x86_64 Compilation ok.
       
Do you need more testing ?

Regards,
Fabian
