	  This Kconfig allows the kernel to automatically patch the

	  errata required by the execution platform at run time. The

	  code patching is performed once in the boot stages. It means

	  that the overhead from this mechanism is just taken once.

	  code patching overhead is minimal, as it's only done once

	  at boot and once on each module load.
