The diffstat can be logically grouped into the following 3 sets:
1. IBS Memory Profiler: A bunch of x86 specific files got included in this
version when I switched from NMI to using fixed interrupt for IBS Memory Profiler.
2. Many of the files in mm and all in sched are touched due to moving of NUMA
Balancing tiering mode (kernel.numa_balancing=2) from scheduler to pghot as hint
fault source.
3. Then rest of the changes are due to pghot core.
