The patch adds fragments caused by rh_alloc_align() back to free list, instead
of allocating the whole chunk of memory.  This will greatly improve memory
utilization managed by rheap.

It solves MURAM not enough problem with 3 UCCs enabled on MPC8323.

For what it is worth:
I have tested this patch and it solves the problem with 3 UCCs
as ethernet for me. This fixes a regression introduced after 2.6.20
Please consider for 2.6.22

I noticed Paulus pull request to Linus and this patch wasn't
included. I really want to see it included.

I'll push (or request pull) from Linus tonight for this to go into 2.6.22
