Actually for the build there is no dependencies between patch 1, 13 and the
other ones.

About running the kernel obviously you need the full series to have the CPU
idle working, but if patch 13 is not applied or if it is applied alone, the
kernel won't crash, the only consequence will be that the cpu idle driver won't
be loaded.

If all patches are applied except patch 1 then we could experiment some issues.
However, now the the amount of code is very small in this patch, I planed
to submit it to Russell King's patch system soon.

About patch 13, I agree that if Daniel and Rafael agree to give their acked-by,
it will be easier to handle if you can take it in a single series, but it is not
mandatory.

Thanks,

Gregory
