ttm_page_alloc_debugfs can be registered to output the state of pools. Debugfs file will output number of pages freed from the pool, number of pages in pool now and the lowes number of pages in pool since previous shrink. Signed-off-by:

On AGP system we might allocate/free routinely uncached or wc memory, changing page from cached (wb) to uc or wc is very expensive and involves a lot of flushing. To improve performance this allocator use a pool of uc,wc pages. Pools are protected with spinlocks to allow multiple threads to allocate pages simultanously. Expensive operations are done outside of spinlock to maximize concurrency. Pools are linked lists of pages that were recently freed. mm shrink callback allows kernel to claim back pages when they are required for something else. Fixes: * set_pages_array_wb handles highmem pages so we don't have to remove them from pool. * Add count parameter to ttm_put_pages to avoid looping in free code. * Change looping from _safe to normal in pool fill error path. * Initialize sum variable and make the loop prettier in get_num_unused_pages. * Moved pages_freed reseting inside the loop in ttm_page_pool_free. * Add warning comment about spinlock context in ttm_page_pool_free. Based on Jerome Glisse's and Dave Airlie's pool allocator. Signed-off-by:
