George,

to help your decision whether to ack this: This is pretty low risk,
touching code that's new in 4.3 anyway (i.e. regressions are
much more likely with the rest of this new code than with the
changes here, and can be easily overcome by disabling the new
driver via command line option).

Obvious benefit is that we'll have support for Haswell right from
the beginning.

Due to code freeze, I specifically left those out.

Jan
