Josh Poimboeuf 316e4a1652 x86/speculation: Include unprivileged eBPF status in Spectre v2 mitigation reporting ... commit 44a3918c82 upstream. With unprivileged eBPF enabled, eIBRS (without retpoline) is vulnerable to Spectre v2 BHB-based attacks. When both are enabled, print a warning message and report it in the 'spectre_v2' sysfs vulnerabilities file.
