Don't disable it, just don't touch it or any of its mappings. Leave it *alone*, and use swiotlb. That'll maximise the ability to recover stuff from the kexec kernel (since for one you may want to dump the gart when a 3d app goes kerblam)
How about LinuxBIOS + Kernel ===> Final kernel path? someday EFI(PEI) + Kernel ===> Final kernel path need that too. or the normal kexec path still could have clean shutdown.
