NTO profile's default parameter workloadHints.perPodPowerManagement = false seems to be hitting kernel taint bit 2 in nodes using x86_energy_perf function

This feature activates the x86_energy_perf function in the node(s) where the profile is applied, and if this function is enabled and available in the CPUs of the node(s), then these nodes are tainted with taint bit 2 (TAINT_CPU_OUT_OF_SPEC) (i.e., the kernel is running on a processor or system that is out of specification).

Since the default NTO profiles deployed by NTO are not changing the value of this parameter, this means all nodes running default NTO profiles are tainted with taint bit 2.

OCP 4.13

Always, starting 4.13

1. Deploy a OCP cluster using IPI
2. Check NTO profiles created by default (e.g. the ones for master nodes). They are hitting the kernel taint
3. Create a PerformanceProfile setting workloadHints.perPodPowerManagement = true, e.g. in worker nodes. The kernel taint disappear (you need to wait until the MCP are updated and the nodes are rebooted with the new config).
