SubjectRe: Need kernel patch to compile with Intel compiler

Yep. And Intel added a bunch of them to their compiler so that they
could build a kernel with it.

The Intel compiler is quite good at optimizing for their processors (and
ironically for AMD ones as well). However, I think that a lot of the
gains come from the vectorizer, which of course can't be used with
kernel code.
