Peter Zijlstra 89bc853eae objtool: Find unused ENDBR instructions ... Find all ENDBR instructions which are never referenced and stick them in a section such that the kernel can poison them, sealing the functions from ever being an indirect call target. This removes about 1-in-4 ENDBR instructions.
