It's pretty simple - it's just piplining.  During the -rc's we
accumulate stuff for the next release in linux-next and in -mm.  During
the 2.6.x->2.6.x+1-rc1 merge window we transfer that material into
mainline then the cycle starts again.

So new code which turns up during the merge window is a problem.  It
should be reviewed, integrated on top of the already-pending work and
should get some testing in linux-next.  But during the patch-merging
chaos nobody has the time or a suitable tree upon which to be doing
that.

Yes, but all the stuff which is going in now has been reviewed and has
had testing in linux-next and/or -mm.  (In theory).

erk.

Well I got it all merged up relatively easily but I don't know what it
does and I haven't looked at it yet.

It will take some urgent effort from reviewers and, it appears, arch
maintainers to be able to get this over the line.  Even then it wom't
have had any linux-next testing.  This should all have started weeks
ago!
