Linux Kernel Developers Discuss Dropping x32 Support (phoronix.com)
An anonymous reader shared a report: It was just several years ago that the open-source ecosystem began supporting the x32 ABI, but already kernel developers are talking of potentially deprecating the support and for it to be ultimately removed..
[...] While the x32 support was plumbed through the Linux landscape, it really hasn't been used much. Kernel developers are now discussing the future of the x32 ABI due to the maintenance cost involved in still supporting this code but with minimal users. Linus Torvalds is in favor of sunsetting x32 and many other upstream contributors in favor of seeing it deprecated and removed.

Perhaps you could not be retarded and just know this?
X32 is a stupid version of 64 bit that uses 32-bit pointers.
Never understood who thought this was a good idea.
People who care about memory footprint? Linux is used in some pretty small systems, still. If you have far, far less than 4GB you not only don't need 64-bit addressing, you need to not waste 4 bytes on every pointer.
Why not just use x86? More registers (and x64 has a lot more registers) can make a real performance impact.
Socialism: a lie told by totalitarians and believed by fools.
An x64 processor is expensive, large, and power-hungry for modern "pretty small systems." If you have far, far less than 4GB, you've probably moved to 32-bit ARM.
