Jiri Kosina bb4b3b7762 x86/speculation: Propagate information about RSB filling mitigation to sysfs 
If spectrev2 mitigation has been enabled, RSB is filled on context switch
in order to protect from various classes of spectrev2 attacks.

If this mitigation is enabled, say so in sysfs for spectrev2.
