Changing update_mmu_cache() to always call flush_dcache_icache_page()
fixes it, though a better performing fix would probably be to add an
exception table entry for the dcbst.

I can confirm that this seems to fix it.

Might be better to avoid the flush when the page isn't readable ?

Sure, that'd work.  I was trying to avoid a tablewalk to determine that, 
not noticing the pte argument staring me in the face. :-P
