[PATCH 05/13] Hide some of "struct elf_prstatus" behind #ifdef __KERNEL__

[Palmer Dabbelt]

This one scares me: while I can't find any system calls that directly
take this as an argument, a comment in 

  "
   Generic ptrace interface that exports the architecture specific
   regsets using the corresponding NT_* types (which are also used in
   the core dump).  Please note that the NT_PRSTATUS note type in a
   core dump contains a full 'struct elf_prstatus'. But the
   user_regset for NT_PRSTATUS contains just the elf_gregset_t that is
   the pr_reg field of 'struct elf_prstatus'. For all the other
   user_regset flavors, the user_regset layout and the ELF core dump
   note payload are exactly the same layout.
  "

seems to indicate that it's possible to see this sometimes.  Since
this would only be visible to userspace in a somewhat convoluted
manner, I'm going to try and keep it as it was.
