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 "
