For the vmcoreinfo variables document, I personally think it might be
not necessary. The reason is that all the old varialbles are exported
with the name of themselves. We know what they are or what they
represent since they are all kernel symbols or macro. Only this me_mask,
it's a local variable and store the value of sme_me_mask for now, may
store more info later like Petr mentioned, and also will store the memory
encryption information of TME (which is intel's transparent memory encryption).
We can add code comment around to tell these.

Personal opinion.

Thanks
Baoquan
