Re: [RFC] Rename various 'IA32' uses in arch/x86/ code

The issue with that is that "compat" is a cross-architecture feature of the kernel to handle *some* 32-on-64 bit ABI translations. x32 uses *some* but not all of the compat machinery.

It is already confusing when you introduce more than two ABIs (e.g. x32 or MIPS n32) and we need a way to be able to be specific. I suggest using i386 or just use ia32 as a legacy symbol name.
