== What was done engineering wise? ==

We uploaded the linux-3.2.0-12.20 and linux-3.2.0-12.21 kernels in time
for the Alpha-2 milestone.  These uploads contained a rebase to v3.2.2,
enabled CONFIG_GPIO_TWL4030=y for arm[el|hf] to resolve boot issues,
reverted an ath9k regression from v3.2.2, and dropped the seccomp_filter
patch set.

We also announced the opening of the ubuntu-q git repo [1].  This has
been rebased to the latest upstream v3.3-rc2 kernel.  At this time, this
repository is strictly for development and testing purposes only and
will be completely unsupported until we officially release Precise and
the Q development cycle begins.

Any outstanding work items from Alpha-2 were re-targeted to Beta-1.

== What's about to land that might impact the other teams? ==

We've been queuing patches for the first upload post Alpha-2.  This will
include fixes for supporting new broadcom bluetooth devices, mtip32xx
driver updates, add vga_switcheroo support for models with nvidia
optimus hybrid graphics, fixes for radeon issues on MacBook Pro 8,2, and
misc regression fixes.
