Description: Information about CPU vulnerabilities
* - 'Mitigation: Clear CPU buffers'
- The processor is vulnerable and the CPU buffer clearing mitigation is
enabled.
+ * - 'Unknown: No mitigations'
+ - The processor vulnerability status is unknown because it is
+ out of Servicing period. Mitigation is not attempted.
+
+Definitions:
+------------
+
+Servicing period: The process of providing functional and security updates to
+Intel processors or platforms, utilizing the Intel Platform Update (IPU)
+process or other similar mechanisms.
+
+End of Servicing Updates (ESU): ESU is the date at which Intel will no
+longer provide Servicing, such as through IPU or other similar update
+processes. ESU dates will typically be aligned to end of quarter.
If the processor is vulnerable then the following information is appended to
the above information:
netdev_max_backlog

+Maximum number of packets, queued on the INPUT side, when the interface
receives packets faster than kernel can process them.

- Enable this if you want to support 64bit kernel on PA-RISC platform.
-
- At the moment, only people willing to use more than 2GB of RAM,
- or having a 64bit-only capable PA-RISC machine should say Y here.
-
- Since there is no 64bit userland on PA-RISC, there is no point to
- enable this option otherwise. The 64bit kernel is significantly bigger
- and slower than the 32bit one.
