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?
