linux: 3.0.0-23.39 -proposed tracker

All builds are complete, packages in this bug can be copied to -proposed.

Derivative packages from packages here can be worked on, the following tracking bugs were opened for them:
linux-ti-omap4 - bug 1026883

Backport packages from packages here can be worked on, the following tracking bugs were opened for them:
linux-lts-backport-oneiric (lucid) - bug 1026884

Confirmed that the kernel build works in on the Ubuntu Cloud Images running on EC2. I verified it on two seperate EC2 instances.

ubuntu@domU-12-31-39-0E-0C-12:~$ uname -a

Confirmed on AMD64 as well.

ii linux-image-virtual 3.0.0.17.20 Linux kernel image for virtual machines

The following packages ended up in the wrong component in the -proposed pocket:

linux-image-3.0.0-23-virtual 3.0.0-23.39 - is in universe instead of main

Once this is fixed, set the promote-to-proposed to Fix Released again

Overrides fixed by Colin.

I got a hard failure on AWS m1.small, while running the seccomp tests:

Repeating test show that issues seem to be related with the version of Xen running on the EC2 host and not with the guest kernel. 3.0.3 shows a #GP on writing cr4 while 3.4.3 was working ok. And more this failed with older (as old as initial release) kernels as well as it did on the new one (we probably don't know which Xen version this was happening on. So I would say this should not delay the release of this update.

Bug1026853 has been created against QRT to track the failing seccomp_tests as it has been shown to occur on older versions of the kernel, and it currently seems likely that it is related to the hosts Xen version.

tagging qa-testing-passed, given the discussion on #ubuntu-kernel and the comments here.
