parentCoccicheck: Remove memcpy to struct assignment test (diff)
scripts: objdiff: detect object code changes between two commits
objdiff is useful when doing large code cleanups. For example, when removing checkpatch warnings and errors from new drivers in the staging tree. objdiff can be used in conjunction with a git rebase to confirm that each commit made no changes to the resulting object code. It has the same return values as diff(1). This was written specifically to support adding the skein and threefish cryto drivers to the staging tree. I needed a programmatic way to confirm that commits changing >90% of the lines didn't inadvertently change the code. Temporary files (objdump output) are stored in /path/to/linux/.tmp_objdiff 'make mrproper' will remove this directory.
