[$] Extending the mempolicy interface for heterogeneous systems

Description:
Non-uniform memory access (NUMA) systems are organized with their CPUs
grouped into nodes, each of which has memory attached to it.  All memory in
the system is accessible from all CPUs, but memory attached to the local
node is faster.  The kernel's memory-policy
("mempolicy") interface allows threads to inform the kernel about how
they would like their memory placed to get the best performance.  In recent
years, the NUMA concept has been extended to support the management of
different types of memory in a system, pushing the limits of the mempolicy
subsystem.  In a remotely presented session at the 2024 Linux Storage,
Filesystem, Memory Management, and BPF Summit , Gregory Price discussed
the ways in which the kernel's memory-policy support should evolve to
handle today's more-complex systems.
