Why does REGSET_CET64 alias on REGSET_TLS?

In x86_64_regsets[], there is no [REGSET_TLS].  The core dump code
cannot handle holes in the array.

Is there a fundamental (ABI) reason for that?

to "CET" (which is a well-known acronym for "Central European Time"),
not to CFE?

I don't know if I can change that, will find out.

So what I'd suggest is something pretty simple: to use CFT/cft in kernel internal 
names, except for the Intel feature bit and any MSR enumeration which can be CET 
if Intel named it that way, and a short comment explaining the acronym difference.

Or something like that.
