In particular, this patchset gets rid of data structures built using assembly, moves the selection of an atomic 5-byte NOP into the same infrastructure as everything else, and does some small amount of 32- vs. 64-bit unification. Comments appreciated. [PATCH 1/3] x86, percpu: Use ASM_NOP4 instead of hardcoding P6_NOP4 [PATCH 2/3] x86, cpu: Clean up and unify the NOP selection infrastructure [PATCH 3/3] x86, cpu: Change NOP selection for certain Intel CPUs -- 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/
