There is the "clflush" instruction, but not all x86 CPUs support it. You need to check the CPUID flag to know for sure (/proc/cpuinfo will show a "clflush" flag if it is supported). - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
