[$] Support for private memory nodes

Gregory Price started his session in the memory-management track of the2026 Linux Storage,Filesystem, Memory Management, and BPF Summit by saying that, incurrent kernels, if a NUMA node has memory, the assumption is that anybody canmake use of it. He is trying to implement the opposite policy - to makesome memory off-limits for all processes except those designed specificallyto use it. The session was used to present his goals and to discuss howthey might be implemented.
