Allwinner devices are OK, Exynos devices (except 4210) are OK.

Well the kernel I'm testing is just current Linux next cross
compiled omap2plus_defconfig kernel. I do have few more config
options enabled like LOCKDEP and DEBUG_ATOMIC_SLEEP, but I
doubt they matter here :)

Then I'm using gcc-7.3.0 and binutils-2.30 built with the
buildall.git scripts:

git://git.infradead.org/users/segher/buildall.git

If you still need binaries, let me know.

Do you know which arm devices are working with your patch?

Regards,

Tony
