[PATCH v2 0/2] vDSO: Always reject undefined references during linking

Posted by Thomas Weißschuh 11 months, 1 week ago

Instead of using a custom script to detect and fail on undefined
references, use --no-undefined for all VDSO linker invocations.

Drop the now unused checkundef.sh scripts.

These patches can be picked up by the architecture maintainers.
