    ---8<------------------------------------------------------------

    From: Sudip Mukherjee <sudipm.mukherjee@gmail.com>

    commit 601f1db653217f205ffa5fb33514b4e1711e56d1 upstream.

    The build of m32104ut_defconfig for m32r arch was failing for long long
    time with the error:

    ERROR: "memory_start" [fs/udf/udf.ko] undefined!
    ERROR: "memory_end" [fs/udf/udf.ko] undefined!
    ERROR: "memory_end" [drivers/scsi/sg.ko] undefined!
    ERROR: "memory_start" [drivers/scsi/sg.ko] undefined!
    ERROR: "memory_end" [drivers/i2c/i2c-dev.ko] undefined!
    ERROR: "memory_start" [drivers/i2c/i2c-dev.ko] undefined!

    As done in other architectures export the symbols to fix the error.
