kernel: x86/bugs: Enable IBPB flush on BPF JIT allocation

A flaw was found in the Linux kernel. This vulnerability involves an incomplete defense against Spectre-v2, a type of attack that can expose sensitive information by exploiting how modern processors predict future operations. Specifically, when the Berkeley Packet Filter BPF Just-In-Time JIT...
