x86/bugs: Fix reporting of LFENCE retpoline
[ Upstream commit d1cc1baef67ac6c09b74629ca053bf3fb812f7dc ]
The LFENCE retpoline mitigation is not secure but the kernel prints
inconsistent messages about this fact. The dmesg log says 'Mitigation:
LFENCE', implying the system is mitigated. But sysfs reports 'Vulnerable:
LFENCE' implying the system (correctly) is not mitigated.
Fix this by printing a consistent 'Vulnerable: LFENCE' string everywhere
when this mitigation is selected.
