Besides x86 and powerpc I plan to eventually convert all other
architectures, although this will be a slow process, starting with the
easier ones once the infrastructure is merged.  The process to convert
architectures is roughtly:

 (1) ensure there is no set_fs(KERNEL_DS) left in arch specific code
 (2) implement __get_kernel_nofault and __put_kernel_nofault
 (3) remove the arch specific address limitation functionality

The one to really watch out for is sparc; I have something in that
direction, will resurrect as soon as I'm done with eventpoll analysis...

I can live with this series; do you want that in vfs.git#for-next?

Either that or a separate tree is fine with me.  It would be good to
eventually have a non-rebased stable tree so that other arch trees
can work from it, though.
