Hi! H. Peter Anvin and all

I use the name "x86_32" to describe it in original commit 03f5781be2c7
("bpf, x86_32: add eBPF JIT compiler for ia32"), but almost all following
committers and contributors use the world "x32", I think it is short format
for x{86_}32.

Yes, I agree, "x32" isn't the right name here, I think "x32" is well known
as a ABI, so maybe we should use "x86_32" or ia32 in future communication.

Which one is the best name here? x86_32 or ia32 or anything other?

Thanks!
