“The X86_NATIVE_CPU Kconfig build time option has been merged for the Linux 6.16 merge window as an easy means of enforcing “-march=native” compiler behavior on AMD and Intel processors to optimize your kernel build for the local CPU architecture/family of your system.
The CONFIG_X86_NATIVE_CPU option is honored if compiling the Linux x86_64 kernel with GCC or LLVM Clang when using Clang 19 or newer due to a compiler bug with the Linux kernel on older compiler versions.”

“Unlike Kpatch and Ksplice, which patch the running kernel without rebooting, Live Update Orchestrator takes a hybrid approach. While it requires a reboot, it focuses on keep critical devices running, which minimizes the side effects of the update.”
- Google is developing Live Update Orchestrator, a new system for updating the Linux kernel with minimal downtime.
- This technology is focused on cloud environments, allowing hypervisors to be updated without completely interrupting running virtual machines.
- Live Update is a specialized reboot process that keeps certain devices operational through kernel transitions.
- A new device infrastructure (dev_liveupdate) is introduced to integrate with the Live Update Orchestrator system.

What type of BS is this !!?
Rejecting commits and removing developers based on nationality !!! What does even has nationality to do with open-source contributions !!? If the code is good, non-malicious and runs it should be accepted …
The kernel leadership is ridiculous…
