Linux 2.6.32.48

I'm announcing the release of the 2.6.32.48 kernel.

It fixes a number of reported build errors with the 2.6.32.47 kernel.
If you aren't hitting them, then there's no need for you to upgrade at
this point in time.

The updated 2.6.32.y git tree can be found at (NOTE THE ADDRESS CHANGE):
        git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-2.6.32.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;a=shortlog;h=refs/heads/linux-2.6.32.y

thanks,

greg k-h
