Hi Ivan,

I have no idea - I did not try EABI. I wasted too much time with 4.2.1
with EABI to try it again. Maybe this patch is not required for everyone
but it was required for me.

Soft float does not compile for OABI for other reasons (see the other
bug I submitted) too so who knows.

I had 4.2.1 OABI working, but a kernel I compiled with it does not boot.
4.1.2 compiles the same kernel with a working result.
