[$] The future of 32-bit support in the kernel

Arnd Bergmann started his OpenSource Summit Europe 2025 talk with a clear statement of position: 32-bitsystems are obsolete when it comes to use in any sort of new products. Theonly reason to work with them at this point is when there is existinghardware and software to support. Since Bergmann is the overall maintainerfor architecture support in the kernel, he is frequently asked whether32-bit support can be removed. So, he concluded, the time has come to talkmore about that possibility.
