Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi! For S3 wakeup I need identity mappning. There's acpi_create_identity_pmd(), but its broken: it only creates 4MB worth on mappings, and you get really *nasty to debug* crashes if you enable enough options in your kernel. Question is how to fix it nicely. I thought about killing zap_low_mappings and then reusing swapper_pg_dir for that purpose. Is there some problem with that? Pavel -- Worst form of spam?
