The problem seems to be that update_mmu_cache() is called on a guard page with no access rights. 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. -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
