David Hildenbrand 750b317f85 agp: efficeon: no need to set PG_reserved on GATT tables ... Patch series "mm: PG_reserved cleanups and documentation", v2. I was recently going over all users of PG_reserved. Short story: it is difficult and sometimes not really clear if setting/checking for PG_reserved is only a relict from the past. Easy to break things. I guess I now have a pretty good idea wh things are like that nowadays and how they evolved. I had way more cleanups in this series inititally, but some architectures take PG_reserved as a way to apply a different caching strategy (for MMIO pages). So I decided to only include the most obvious changes (that are less likely to break something). So the big chunk of manual SetPageReserved users are MMIO/DMA related things on device buffers. Most notably, for device memory we will hopefully soon stop setting PG_reserved. Then the documentation has to be updated. This patch (of 9): The l1 GATT page table is kept in a special on-chip page with 64 entries. We allocate the l2 page table pages via get_zeroed_page() and enter them into the table. These l2 pages are modified accordingly when inserting/removing memory via efficeon_insert_memory and efficeon_remove_memory. Apart from that, these pages are not exposed or ioremap'ed. We can stop setting them reserved (propably copied from generic code).
