From: Thadeu Lima de Souza Cascardo <[email protected]> Commit b789ef518b2a7231b0668c813f677cee528a9d3f tests for cmpxchg_double support in the SLUB code and it breaks UML builds with SLUB. Since UML does not support checking for CPU features, disable CMPXCHG_DOUBLE just like CMPXCHG_LOCAL is disabled for UML.
