Cleaning Up A Mess: Linux 6.9 Likely To Land Rework Of x86 CPU Topology Code

Longtime Linux kernel developer Thomas Gleixner with Intel-owned Linutronix has been spending much time over the past several months reworking the Linux kernel's x86 CPU topology evaluation code. This is to clean-up a mess of aging kernel code as well as some areas of the code being incorrect in today's era of hybrid Intel Core processors with a mix of P / E cores with the E cores lacking SMT/HT and thus throwing off prior kernel assumptions. With the code now queued up in a TIP branch today, it looks like that CPU topology rework could be good to go with Linux 6.9...
