I wonder if we can improve things here so that we use the runtime-detected cacheline size rather than the compile-time size. I guess not, given that the offsets into the percpu area are calculated at build-time. Did you work out how much space this change will actually save? It should be available by suitable crunching on the nm and objdump output. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
