NUMA has been disabled for the past few years and no-one has noticed
Backport candidate, Requires assessmentPublicBUG

Description

As I was doing some performance load tests, I discovered that somehow all the NUMA configuration was removed accidentally from the kernel build toolset! This means that any memory hungry things (conntrack, I'm looking at you) was significantly throttled.

Pull request attached which re-enables it, and also enables kexec so we can potentially enable fast reboots.

That was generated by running make defconfig, enabling numa, and saving it back. BUILD_BIN2C is related to kexec.
