| config PID_IN_CONTEXTIDR | |
| bool "Write the current PID to the CONTEXTIDR register" | |
| depends on CPU_COPY_V6 | |
| help | |
| Enabling this option causes the kernel to write the current PID to | |
| the PROCID field of the CONTEXTIDR register, at the expense of some | |
| additional instructions during context switch. Say Y here only if you | |
| are planning to use hardware trace tools with this kernel. | |
| config DEBUG_SET_MODULE_RONX | |
| bool "Set loadable kernel module data as NX and text as RO" | |
| depends on MODULES | |
| ---help--- | |
| This option helps catch unintended modifications to loadable | |
| kernel module's text and read-only data. It also prevents execution | |
| of module data. Such protection may interfere with run-time code | |
| patching and dynamic kernel tracing - and they might also protect | |
| against certain classes of kernel exploits. | |
| If in doubt, say "N". | |
