[parisc-linux] binfmt_som

[Matthew Wilcox <Matthew.Wilcox@genedata.com>]

I've checked in a binfmt_som which I think might work.  However,
it definitely won't work until someone defines put_user() & friends
in include/asm-parisc/uaccess.h.

I also inserted a declaration of start_thread in <asm/processor.h> --
some platforms have it as a macro, some have it as a function, so I
think linking will now fail with that as an undefined symbol.
