Meantime I'll investigate the kprobes test failures I see (which actually looks like cache/TLB issues and not test code problems after all).OK, btw, I couldn't reproduce the kprobes test failure with CONFIG_DEBUG_RODATA=y on qemu...
That's because it's a problem with caches which qemu doesn't emulate. I worked out the cause and posted a patch... http://lists.infradead.org/pipermail/linux-arm-kernel/2017-February/489517.html -- Tixy
