  update Linux headers from kvm/next (2015-06-05 17:10:02 +0200)

Apologies for the very large pull request, mostly due to the two main
topics (dirty bitmap + SMM) being reviewed more or less at the same time.

----------------------------------------------------------------
* KVM error improvement from Laurent
* CONFIG_PARALLEL fix from Mirek
* Atomic/optimized dirty bitmap access from myself and Stefan
* BUILD_DIR convenience/bugfix from Peter C
* Memory leak fix from Shannon
* SMM improvements (though still TCG only) from myself and Gerd, acked by mst
