[ Upstream commit 0f8ed994575429d6042cf5d7ef70081c94091587 ]
Building nios2:allmodconfig fails as follows (each symbol is only listed once).
ERROR: "__ashldi3" [drivers/md/dm-writecache.ko] undefined! ERROR: "__ashrdi3" [fs/xfs/xfs.ko] undefined! ERROR: "__ucmpdi2" [drivers/media/i2c/adv7842.ko] undefined! ERROR: "__lshrdi3" [drivers/md/dm-zoned.ko] undefined! ERROR: "flush_icache_range" [drivers/misc/lkdtm/lkdtm.ko] undefined! ERROR: "empty_zero_page" [drivers/md/dm-mod.ko] undefined!
The problem is seen with gcc 7.3.0.
Export the missing symbols.
