Ingo, please pull the latest master git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/glommer/linux-2.6-x86-integration.git master
into your tip/auto-x86-next tree
It contains integration of the dwarf headers.
Thanks!

thanks, applied. Note, for me to be able to pull it, please base the
tree either against Linus's tree (if it can merge cleanly to
tip/master), or base it against tip/x86/core.
auto-x86-next is a throwaway branch that gets regenerated, if i pulled
from you i'd instantiate that throwaway merge commit as well in the
'persistent' (append only) tip/x86/core as well.
So i cherry-picked out the commits from your tree.
