Josh Poimboeuf 316e4a1652 x86/speculation: Include unprivileged eBPF status in Spectre v2 mitigation reporting
commit 44a3918c8245ab10c6c9719dd12e7a8d291980d8 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.
