This change is incorrect.

LM22 relocations do not get emitted for the "medlow" code model, which
is what is explicitly specified on the kernel compiler command line
for sparc64 via "-mcmodel=medlow".

Someone this person is using incorrect CFLAGS when building their
module, and that's why they have this problem, because the compiler's
default code model on sparc64 can generate those relocations.
