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"
