I'm announcing the release of the 3.2.43 kernel.

All users of the 3.2 kernel series should upgrade.

The updated 3.2.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-3.2.y
and can be browsed at the normal kernel.org git web browser:
http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git

The diff from 3.2.42 is attached to this message.

Ben.
