Peter Zijlstra 5891271055 x86/ibt,bpf: Add ENDBR instructions to prologue and trampoline ... With IBT enabled builds we need ENDBR instructions at indirect jump target sites, since we start execution of the JIT'ed code through an indirect jump, the very first instruction needs to be ENDBR. Similarly, since eBPF tail-calls use indirect branches, their landing site needs to be an ENDBR too. The trampolines need similar adjustment.
