From: Ben Hutchings <ben@xxxxxxxxxxxxxxx> The vulnerabilties/l1tf attribute was added by commit 17dbca119312 "x86/speculation/l1tf: Add sysfs reporting for l1tf", which has already been backported to 3.16, but only documented in commit d90a7a0ec83f "x86/bugs, kvm: Introduce boot-time control of L1TF mitigations", which has not and probbaly won't be. Add just that line of documentation for now.
