x86: this_cpu_cmpxchg and this_cpu_xchg operations
Provide support as far as the hardware capabilities of the x86 cpus allow. Define CONFIG_CMPXCHG_LOCAL in Kconfig.cpu to allow core code to test for fast cpuops implementations. V1->V2: - Take out the definition for this_cpu_cmpxchg_8 and move it into a separate patch. tj: - Reordered ops to better follow this_cpu_* organization. - Renamed macro temp variables similar to their existing neighbours.
