Subject: [PATCH 0/3] Some TIF_IA32 fixes

At some point I'd like to remove TIF_IA32 entirely and replace it with
just user_64bit_mode and a per-mm configuration.  In the mean time,
this fixes some incorrect uses.

Ingo, Thomas, Peter, if you like these, please ack the first one and apply
the other two.  The first one will conflict with the pile of entry changes
that I'll send a pull request for in a few days.  (Alternatively, you can
take all three and fix the conflict yourself -- it's trivial.)

Andy Lutomirski (3):
  x86_64, entry: Remove a bogus ret_from_fork optimization
  x86_64, ptrace: Remove checks for TIF_IA32 when changing cs and ss
  x86_64, copy_thread: Fix CLONE_SETTLS bitness
