This is a pretty big change, before merging I would like to get more
eyes on it. Please make sure you get more reviews on the code and the
general concept. A few things I noticed while looking at it:

* You put a lot of code into #define CONFIG_CRASH_DUMP. Isn't the same
  approach necessary to for KEXEC?

* Please get rid of all the pr_debug stuff.

* I think it makes sense to put the functions to access the IOMMU
  configuration values of the old kernel into a new file. This is better
  than adding over 1000 new lines to intel-iommu.c

* I have seen your new single-patch for this change. A single patch with
  more than 1200 changed lines is not something anyone is willing to
  review. Please split the patches again in a meaningful and bisectable
  way.


Thanks,

        Joerg
