I believe just reverting this particular git commit 69a07f0b117a40fcc1a479358d8e1f41793617f2 does it. Doing it on top of v2.6.39-rc1: ated: 2427 deleted: 1229), skipping inexact rename detection Finished one revert. [stable/ttm.pci-api-rc2 97bbc38] Revert "ttm: Utilize the DMA API for pages that have TTM_PAGE_FLAG_DMA32 set." 1 files changed, 3 insertions(+), 23 deletions(-) shows it to being a nice easy backout.
