This really doesn't look like a good idea:  Firstly the default of
asm-generic/types.h should *not* be int-ll64, because that's for 32 bit
only and most processors are moving towards 64 bit.  Secondly parisc
currently only has a 32 bit userspace, which is why the file is a simple
include of int-ll64.h; however, people are working on 64 bit userspace
(albeit very slowly) and that file would then have to change.  If we
take the file away someone will forget to add the changed file back.
