The latest version of modinfo fails to compile score architecture
targets with the following error.
FATAL: The relocation at __ex_table+0x634 references
section "__ex_table" which is not executable, IOW
the kernel will fault if it ever tries to
jump to it. Something is seriously wrong
and should be fixed.
The probem is caused by a bad label in an __ex_table entry.

This might be a candidate for -stable.
