Looks like some git problem; git pull from your repo into my branch says everything is uptodate (git merge also says the same thing). However, my branch still has the older struct (where lapic is not a pointer). git log shows the relevant commit. git checkout -f doesn't help either.

Thanks; without the stack reduction patch, this just looked to me like adding a build break and not changing anything else.
