From: Greg KH <gre...@linuxfoundation.org> 3.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Suresh Siddha <suresh.b.sid...@intel.com> commit 0b91f45b23cb73ce11acdc3cf4c6efd4441e3b3e upstream. Signal delivery compat path may not have the 'TS_COMPAT' flag (that flag indicates how we entered the kernel). So use test_thread_flag(TIF_IA32) instead of is_ia32_task(): one of the functions of TIF_IA32 is just what kind of signal frame we want.
