Hi all,

After merging the btrfs tree, today's linux-next build (nds32 allyesconfig
nds32le-gcc8) failed like this:

nds32le-linux-ld: fs/btrfs/lzo.o: in function `lzo_compress_pages':
(.text+0x226): undefined reference to `__umoddi3'
nds32le-linux-ld: (.text+0x22a): undefined reference to `__umoddi3'
nds32le-linux-ld: (.text+0x660): undefined reference to `__umoddi3'
nds32le-linux-ld: (.text+0x664): undefined reference to `__umoddi3'

Probably Caused by commit

  0078783c7089 ("btrfs: rework lzo_compress_pages() to make it subpage compatible")

This caused build failures in several other 32 bit architecture builds.
