* 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.

This option will show the mapping relationship between hardware irq
|
|
numbers and Linux irq numbers. The mapping is exposed via debugfs
|
|
in the file "irq_domain_mapping".

If you don't know what this means you don't need it.

---help---
|
|
|
|
Sparse irq numbering is useful for distro kernels that want
|
|
to define a high CONFIG_NR_CPUS value but still want to have
|
|
low kernel memory footprint on smaller machines.
|
|
|
|
( Sparse irqs can also be beneficial on NUMA boxes, as they spread
|
|
out the interrupt descriptors in a more NUMA-friendly way. )
|
|
|
|
If you don't know what to do here, say N.
