Please first of all explain why the interfaces in asm/flushtlb.h can't be used here (at least when flushing entire pages). Because - as said before - for a complete fix you'd need to deal with the CLFLUSH use(s) elsewhere in the system too. Btw, isn't the !iommus_incoherent check in that function inverted? I.e. why would we _not_ need to flush caches when IOMMUs are not coherent (and why would flushing be needed when they're coherent anyway)?
