The patch won't be used. In the meantime Ilya provided a gcc 9 and
kernel patch which should fix this. The kernel patch is available here
https://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git/commit/?h=features&id=146448524bddbf6dfc62de31957e428de001cbda
and will go upstream during the next merge window.

Note: this obviously also requires to update the gcc 9 version in
Fedora, so it contains Ilya's patch, to be able to compile the kernel.

Thanks,
Heiko
