Merge branch 'parisc-4.20-4' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc fix from Helge Deller: "On parisc, use -ffunction-sections compiler option when building 32-bit kernel modules to avoid sysfs-warnings when loading such modules. This got broken with kernel v4.18" * 'parisc-4.20-4' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: Enable -ffunction-sections for modules on 32-bit kernel
