Do you intend to prevent or allow OOM under that flag? I personally

The tile tool chain uses the .eh_frame information for backtracing.
The vmlinux build drops any .eh_frame sections at link time, but when
present in kernel modules, it causes a module load failure due to the
presence of unsupported pc-relative relocations. When compiling to
use compiler feedback
These are now provided in asm-generic/module.h, so clean up warning
by not re-defining them in module.c.
