On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,

DESCRIPTION
* CVE-2020-8694: Platypus Attack Mitigation.
A side-channel attack utilizing the Intel RAPL subsystem driver may
cause an information leak. This may allow an unprivileged user to
view confidential data.
* Add ftrace safety guard for existing Ksplice updates.
Ftrace is generally incompatible with Ksplice's patching process; it must
be disabled when patches are applied. Prevent crashes in patching due to
functions under active ftrace while patching.
* Clean up ftrace safety guard for existing Ksplice updates.
Ftrace is generally incompatible with Ksplice's patching process; it must
