[PATCH] x86_64: Reject SRAT tables that don't cover all memory
Broken BIOS on Iwill 8way systems reports these and it causes the bootmem allocator to crash. Add a sanity check if all the PXMs in the SRAT table cover all memory as reported by e820. If the sanity check fails the SRAT is rejected and the code will fall back to discover the NUMA topology using the K8 northbridge registers when applicable.
