I noticed tip started failing in my CI environment which tests on QEMU. The failure bisected to commit 425209e0abaf2c6e3a90ce4fedb935c10652bf80
It reproduces running ppc64le QEMU on a x86-64 box. On Ubuntu:
sudo apt-get install qemu-system-ppc gcc-powerpc64le-linux-gnu
make ARCH=powerpc pseries_le_defconfig
make ARCH=powerpc CROSS_COMPILE=powerpc64le-linux-gnu- vmlinux -j4
qemu-system-ppc64 -nographic -vga none -kernel vmlinux
