The point I don't like about update_mmu_cache() is that it's called _after_ set_pte(). Practically it's maybe not a problem right now, but the cache synchronization should happen before set_pte().
update_mmu_cache() is specifically supposed to always occur before anyone could try to use the mapping created.
If this is ever violated, it will be fixed because it is a BUG().
So I don't see what you're worried about.
If the above were not true, sparc64 wouldn't be able to compile a kernel successfully. :-) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
