alpha: __udiv_qrnnd should be exported

montjoie · mattst88 · commit e4b016f4b441 · 2021-07-25T20:55:40.000-07:00
When building an alpha kernel with mpi set as module, I hit this build
error:
ERROR: "__udiv_qrnnd" [lib/mpi/mpi.ko] undefined!
make[2]: *** [scripts/Makefile.modpost:92: __modpost] Error 1
make[1]: *** [Makefile:1266: modules] Error 2

This is due to __udiv_qrnnd not exported.
