[Cbe-oss-dev] [PATCH] spufs: fix affinity after introduction of node_allowed() calls

[Jeremy Kerr]

From: Andre Detsch <adetsch at br.ibm.com>

This patch fixes affinity reference point placement, which was not being
done in some situations, after the introduction of node_allowed() calls.

The previously used parameter, 'ctx', is just the iterator of the
previous list_for_each_entry_reverse loop, and its value might be
invalid at the end of the loop. Also, the right context to seek
for information when defining the reference ctx location
_is_ the reference ctx.
