I have a ticket open with kernel.org to resolve the issue. But until
then, this mailing is the only place the patches exist.

To build 3.2.28-rt43-rc1 directly, the following patches should be applied:

  http://www.kernel.org/pub/linux/kernel/v3.x/linux-3.2.tar.xz

  http://www.kernel.org/pub/linux/kernel/v3.x/patch-3.2.28.xz

  http://www.kernel.org/pub/linux/kernel/projects/rt/3.2/patch-3.2.28-rt43-rc1.patch.xz

You can also build from 3.2.28-rt42 by applying the incremental patch:
