[PATCH] x86: fix amd64-agp aperture validation
Under CONFIG_DISCONTIGMEM, assuming that a !pfn_valid() implies all subsequent pfn-s are also invalid is wrong. Thus replace this by explicitly checking against the E820 map. AK: make e820 on x86-64 not initdata Signed-off-by: Jan Beulich <jbeulich@novell.com> Signed-off-by: Andi Kleen <ak@suse.de> Acked-by: Mark Langsdorf <mark.langsdorf@amd.com>
