Subject: x86_64 acpi: disable srat when numa emulation succeeds
From: David Rientjes <rientjes@xxxxxxxxxx>

When NUMA emulation succeeds, acpi_numa needs to be set to -1 so that
srat_disabled() will always return true.  We won't be calling
acpi_scan_nodes() or registering the true nodes we've found.
