[$] The future of 32-bit Linux

The news for processors and system-on-chip (SoC) products thesedays is all about 64-bit cores powering the latest computers andsmartphones, so it's easy to be misled into thinking that all 32-bittechnology is obsolete. That quickly leads to the idea of removing supportfor 32-bit hardware, which would clearly make life easier for kerneldevelopers in a number of ways.At the same time, a majority of embedded systems shipped today do use 32-bitprocessors, so a valid question is if this will ever change, or if 32-bitwill continue to be the best choice for devices that do not requiresignificant resources.
