[PATCH] spufs: fix for CONFIG_NUMA

Browse Source 
Based on an older patch from  Mike Kravetz <kravetz@us.ibm.com>

We need to have a mem_map for high addresses in order to make fops->no_page
work on spufs mem and register files.  So far, we have used the
memory_present() function during early bootup, but that did not work when
CONFIG_NUMA was enabled.

We now use the __add_pages() function to add the mem_map when loading the
spufs module, which is a lot nicer.
