If enabled, the program text, rodata, and data parts of the kernel in the permanent mappings created at build time will have appropriate permissions set. Uses extra memory due to page-alignment constraints. If not enabled, all SRAM mappings will allow supervisor mode to read, write, and execute. User mode support requires this.
