Ok, this is another big merge of a number of pending patches, although to some degree the patches have now moved "outwards" from the core, and most of them are in driver land.
There's a lot of network driver updates (have been in -mm and Jeff's testing trees for a while), and Al Viro has been fixing up not just network drivers, but also cursing over parport interfaces ;)
Andrew's patches are all over, from fixing warnings with new versions of
gcc to merging things like the ppc updates he had in his tree, and everything in between.
On and a big ALSA update, along with SCSI updates (big qla update, for
example).
So let's calm down and make sure all the updates are ok.
