If Terry was a co-author of the patch, please add a Co-developed-by:
tag for him in addition to the s-o-b.  Otherwise the meaning of his
s-o-b is unclear.

Boris, James, any objections to the changes below?

I realize that this is supposed to test whether the table point to a
generic hardware error source but everything in our code pertaining to
GHES is called, well, "ghes".

So I'd prefer to call that is_generic_error() or so.

Thx.

I will add "co-developed-by" in V2.

Sure, I'll rename is_ghes_type() to is_generic_error() in v2.
