== What was done engineering wise? ==

As noted in last week's meeting, we've rebased to the first v3.2.1
upstream stable release.  We've also uploaded the 3.2.0-10.17 kernel.
This latest uploaded includes an updated overlayfs patch set,
CONFIG_INTEL_IOMMU_DEFAULT_ON disablement, and an upstream fix to
re-enable USB ports for Dell 1536/1546's.  We're also three
quarters of a way through an extensive kernel configuration review.

We have a large number of work items targeted for the Alpha2 release, of
which 92% (152/165) are completed.  The remaining items are not release

== What's about to land that might impact the other teams? ==
As noted above, we've uploaded the 3.2.0-10.17 kernel.  Please test and
let us know of any issues which you encounter.
