arch/tile: provide PT_FLAGS_COMPAT value in pt_regs
This flag is set for ptrace GETREGS or PEEKUSER for processes that are COMPAT, i.e. 32-bit. This allows things like strace to easily discover what personality to use, for example. Acked-by: Oleg Nesterov <oleg@redhat.com> Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
