commit: 0b91f45b23cb73ce11acdc3cf4c6efd4441e3b3e From: Suresh Siddha <[email protected]> Date: Thu, 14 Jun 2012 18:07:15 -0700 Subject: x86, compat: Use test_thread_flag(TIF_IA32) in compat signal delivery
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.
