Re: [PATCH v14 13/13] virt/steal_governor: Enable the driver

Provide a config option to enable the steal_governor driver.
Since the feature targets paravirtualized environments and requires SMP,
enforce those dependencies. The driver selects CONFIG_PREFERRED_CPU
for the core scheduler mechanisms to work.

It is recommended to build the driver as a module (m) instead of
built-in (y) due to the following reasons:

- Module parameters are read-only after initialization. Building as a
  module allows updating these parameters by simply reloading the module.
  Default module parameters cannot work in all configurations.

- The driver can be completely disabled by unloading the module.

- This feature works best when all VMs operate in a cooperative manner.
  Requiring an explicit module load ensures intentional deployment
  across all VMs by the system administrator.
