12.04 - What does x86 mean for installing a new hardware enablement (HWE) stack in 64 bit Ubuntu


I'd like to install 13.10 (Saucy) hardware enablement (HWE) stack to my Ubuntu 12.04 (64-bit) because I need a newer Linux kernel.


This wiki page explains what "hardware enablement stacks" are. Among other things it says:



Only the -generic x86 kernel flavor ... will be supported...



Also, this answer says:



...This is only recommended for x86 hardware installations...



Is x86 here synonymous to 32-bit/i386 architecture (but not 64-bit/AMD64), or is it i386/AMD64 (but not ARM)?


Can I install this "hardware enablement stack" in a 64-bit/AMD64 Ubuntu? Will it be supported with future updates?



Yes, x86 means amd64 or i386. The reference only the -generic kernel flavor refers to the various kernel packages available; "generic" is the regular kernel, but there are also kernels optimised for virtual machines and low latency, and those other kernels are not supported by the hardware enablement stack.
