From 466ae837424dcc538b1af2a0eaf53be32edcdbe7 Mon Sep 17 00:00:00 2001 From: Shaohua Li Date: Mon, 4 Aug 2008 14:51:30 +0800 Subject: reduce tlb/cache flush times of agpgart memory allocation To reduce tlb/cache flush, makes agp memory allocation do one flush after all pages in a region are changed to uc. All agp drivers except agp-sgi uses agp_generic_alloc_page() for .agp_alloc_page, so the patch should work for them. agp-sgi is only for ia64, so not a problem too.
