As it was suggested by Andy, I'm working on TIF_IA32 flag removal. In this first four places, it's quite trivial to use user_64bit_mode instead of test_thread_flag(). This should fix possible problems for native applications that change their code selector to __USER32_CS, but do not have TIF_IA32 flag.
I still quite don't know what to do with uprobes using ia32_compat check and will make the next patches about ptrace & signals usage of TIF_IA32.
Dmitry Safonov (4): x86/events: down with test_thread_flag(TIF_IA32) x86/intel: down with test_thread_flag(TIF_IA32) x86/intel lbr: down with test_thread_flag(TIF_IA32) x86/oprofile: down with test_thread_flag(TIF_IA32)
