This patch removes the need for struct page for SPE local store and registers from spufs. It also makes the locking much more obvious and no longer relying on the truncate logic black magic for protecting against races between unmap_mapping_range() and new pages faulted in. It does so by switching to a nopfn() handler and using the new vm_insert_pfn() to setup the PTEs itself while holding a lock on the SPE. The nice thing is that this patch actually removes a lot more code than it adds :-) Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org> |
