ok, let me try again. tip:x86/mm2 does not fail on xen testing from Stefano and Konrad. Stefano found booting failure with PV xen with for-x86-boot. for-x86-boot has one patch that is trying to get back an wasted page in pre-allocated BRK and that cause xen pv fails with 2G setup. that patch just uncover one bug in x86/mm2. So questions: 1. do we need to rebase x86/mm2 to fold the two patches in. ? 2. or just put fixes at beginning for-x86-boot ?
