parent[PATCH] sparsemem interaction with memory add bug fixes (diff)
[PATCH] spufs: fix for CONFIG_NUMA
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.
