To get a fix for 2.6.22 to the rheap allocator that was causing multiple
instances of the UCC ethernet driver to fail because it was running out of
memory due to wasting space for aligned requests.
Thanks,
Kumar.

[POWERPC] rheap - eliminates internal fragments caused by alignment
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.
