Subject[PATCH v3 0/2] x86/resctrl: Work around MBM errata
Intel Memory Bandwidth Monitoring (MBM) counters may report system
memory bandwidth incorrectly on some Intel processors. The errata are
reported in erratum SKX99 [1], erratum BDF102 [2] and RDT reference
manual [3].

The errata are worked around using a correction factor table. Since
the correction factor table is not publicly documented anywhere, it's
documented in Documentation/x86/resctrl.rst along with the errata.

1. Erratum SKX99 in Intel Xeon Processor Scalable Family Specification
2. Erratum BDF102 in Intel Xeon E5-2600 v4 Processor Product Family
Specification Update:
3. The errata in Intel Resource Director Technology (Intel RDT) on 2nd
Generation Intel Xeon Scalable Processors Reference Manual:

Change Log:
- Remove unnecessary change in patch 1 (Randy).

- Document the errata and the correction table in resctrl.rst (Boris).
- Address various comments on patch 2 (Boris).
- Change the documentation URLs to stable (Tony).

Documentation: x86: Rename resctrl_ui.rst and add two errata to the
