node_cover_memory() sanity checks the SRAT table by ensuring that all PXMs cover the memory reported in the e820. However, when calculating the size of the holes in the e820, it uses the early_node_map[] which contains information taken from both SRAT and e820. If the SRAT is missing an entry, then it is not detected that the SRAT table is incorrect and missing entries. This patch uses the e820 map to calculate the holes instead of early_node_map[]. comment is from Mel.
