SubjectRe: [PATCH 5/5] uprobes/x86: Fix is_64bit_mm() with CONFIG_X86_X32
* Oleg Nesterov <oleg@redhat.com> [2014-04-19 19:02:02]:

> is_64bit_mm() assumes that mm->context.ia32_compat means the 32-bit
> instruction set, this is not true if the task is TIF_X32.
>
> Change set_personality_ia32() to initialize mm->context.ia32_compat
> by TIF_X32 or TIF_IA32 instead of 1. This allows to fix is_64bit_mm()
> without affecting other users, they all treat ia32_compat as "bool".
>
> TIF_ in ->ia32_compat looks a bit strange, but this is grep-friendly
> and avoids the new define's.
