Linus Torvalds c2109f05b7 Revert "exec: load_script: don't blindly truncate shebang string" 
commit cb5b020a8d upstream.

This reverts commit 8099b047ec.

It turns out that people do actually depend on the shebang string being
truncated, and on the fact that an interpreter (like perl) will often
just re-interpret it entirely to get the full argument list.
