An existing SRAT memory range cannot be found for a CFMWS address range. This causes the addition of a duplicate numa_memblk with a different node id and a subsequent page fault and kernel crash during boot. Note that the issue was initially introduced with [1]. But since phys_to_target_node() was originally used that returned the valid node 0, an additional numa_memblk was not added. Though, the node id was wrong too. Fix this by enabling NUMA_KEEP_MEMINFO for x86 with ACPI and NUMA enabled.
