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

Arnd Bergmann started his Open
Source Summit Europe 2025 talk with a clear statement of position: 32-bit
systems are obsolete when it comes to use in any sort of new products. The
only reason to work with them at this point is when there is existing
hardware and software to support. Since Bergmann is the overall maintainer
for architecture support in the kernel, he is frequently asked whether
32-bit support can be removed. So, he concluded, the time has come to talk
more about that possibility.
