Speaking of which, the recent CONFIG_NR_CPUS addition shows just how bloated all our [NR_CPU] structures are. We need to get serious about using the per cpu data stuff. Going from 32 to 64 was over 500kB on my ppc64 build.
In fact, thinking about this some more, we should make the ".per_cpu" bits emit a table entry instead of some dummy object which takes up space. The table entry would be in the special .per_cpu section still but be just a size value.
We should do this on both SMP and non-SMP and it will shrink the kernel image size in both cases.
I don't have the time to implement this so I'll shut up now :-) - 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/
