Dave, Konrad
I think we need to back out this change as soon as possible. I will follow up the discussion with Konrad on how we should attempt to handle vm passthrough as soon as things settle down a bit over here.
Ok. 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.
Dave, I stuck the revert on
git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/ttm.pci-api-rc2
Please pull for rc2.
Hopefully this week.

Wrong git commit.

It is 69a07f0b117a40fcc1a479358d8e1f41793617f2
CCing the relevant people.
How did you make the machine to do this? Did you just echo XX > to the shrinker?
