Linux memory allocator fix cuts boot initialization time drastically

Original: Linux's Early Boot-Time Physical Memory Allocator Big Speed-Up: ~268s to ~50ms

A patch to Linux's early boot-time physical memory allocator, memblock, reportedly cuts initialization time from roughly 268 seconds to about 50 milliseconds, a speed-up of several thousand times. The improvement is slated for Linux 7.4 and is being discussed as a major optimization for large-memory systems, where slow early boot initialization has long been a pain point for servers and data center machines.

Why now: The dramatic magnitude of the speed-up makes it a striking and unusual kernel optimization
