[Letux-kernel] Unhandled EFAULT with letux kernels built with newer gcc compilers

[H. Nikolaus Schaller]

Hi Will,
I haven't seen the unhandled EFAULT you are describing but
there is something weird with futex on the jz4730. There
is no unhandled fault but a process can get stuck in
the futex system call.

So this may both be related. It may fault on the jz4780 with
newer compiler but work with older and get stuck on jz4730
with older...

I need some time to upgrade my good old cross-toolchains
to something newer (yes, gcc 4.9 is quite old and arm64
already requires gcc 5.1)... I have to modify my own compiler
generator because e.g. cross-tool-ng or prebuilt toolchains
do not fit my requirements for a cross-compiling farm for
multiple architectures. Especially since a toolchain is
more than the C compiler.

BR and thanks,
Nikolaus
