Re: [PATCH] x86-64: disable the GART in shutdown

So my suggestion would be:

(1) implement sysfs platform device based shutdown hooks (preferable
before PCI shutdown)

BTW, it would be better if DMA ram range was registered there too.

(2) make sure GART is never enabled in kernels that are all < 4GB (as
in the kdump kernel). But what to do about AGP?

yeah, AGP bridge will enable GART already.
