* 0day explit mitigation * Memory corruption prevention * Privilege escalation prevention * Buffer over flow prevention * File System corruption defense * Thread escape prevention This may very well be the most intensive inclusion to BrooklynR. This will not be part of an x86 suite nor it will be released as tool kit. The security core toolkit will remain part of kernel base.

|
* without putting the chip back into hardware reset, which also requires
|
|
* a complete re-initialization of all registers.
|
|
*
|
|
* One (undocumented) workaround is to assert and de-assert the PDN bit
|
|
* in the MODE2 register. This workaround can be enabled with the
|
|
* following flag.
|

*
|

* Note that this is not needed in case the clocks are stable

|
* throughout the entire runtime of the codec.
