ok, in that case you can use tip's topical structure and probably bisect
purely x86/gart, which has all x86 gart changes.

I.e. do something like this:

git-checkout tip/x86/gart

build and boot that kernel, if it fails and mainline works then do:

git-bisect reset
git-bisect start
git-bisect good linus/master
git-bisect bad tip/x86/gart

this should drastically reduce the number of bisection steps needed, to
3 or 4 iterations.
