David Howells a94549dd87 lockdown: Lock down tracing and perf kprobes when in confidentiality mode 
Disallow the creation of perf and ftrace kprobes when the kernel is
locked down in confidentiality mode by preventing their registration.
This prevents kprobes from being used to access kernel memory to steal
crypto data, but continues to allow the use of kprobes from signed
modules.
