Subject: [PATCH] x86/ptrace: Remove checks for TIF_IA32 when changing CS and
 SS

The ability for modified CS and/or SS to be useful has nothing
to do with TIF_IA32.  Similarly, if there's an exploit involving
changing CS or SS, it's exploitable with or without a TIF_IA32
check.

So just delete the check.
