From: Suresh Siddha Date: Fri, 15 Jun 2012 01:07:15 +0000 (-0700) Subject: x86, compat: Use test_thread_flag(TIF_IA32) in compat signal delivery X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0b91f45b23cb73ce11acdc3cf4c6efd4441e3b3e;p=linux-beck.git 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.
