For the record, pciutils was GPL and therefore disabled by default since v1.6.2. + Add --disable-cpuid configure flag to work around buggy processor simulators reporting invalid CPUID information. Thanks for Andrew Friedley for reporting the issue. + Fix a racy use of libltdl when manipulating multiple topologies in different threads. Thanks to Andra Hugo for reporting the issue and testing patches. + Fix some build failures in private/misc.h.
