AMD's next generation of EPYC processors support the MPK (Memory
Protection Keys) feature.

AMD documentation for MPK feature is available at "AMD64 Architecture
Programmer’s Manual Volume 2: System Programming, Pub. 24593 Rev. 3.34,
Section 5.6.6 Memory Protection Keys (MPK) Bit".

The documentation can be obtained at the link below:
https://bugzilla.kernel.org/show_bug.cgi?id=206537

This series enables the feature on AMD and updates config parameters
to reflect the MPK support on generic x86 platforms.
