Josh Poimboeuf afc2d635b5 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.
