Subject: [PATCH] x86_64: checking aperture report for node instead of cpu

this one is against x86.git

[PATCH] x86_64: checking aperture report for node instead of cpu

currently when gart iommu is enabled by BIOS or previous we got

"
Checking aperture...
CPU 0: aperture @4000000 size 64MB
CPU 1: aperture @4000000 size 64MB
"
we should use use Node instead.

we will get
"
Checking aperture...
Node 0: aperture @4000000 size 64MB
Node 1: aperture @4000000 size 64MB
"
