I did 3 x86_64 allmodconfig builds without and with the patch (I do -j 80 powerpc64 le hosted cross builds) and it doesn't look like the patch has much impact at all. Without the patch: real 8m41.390s user 587m25.249s sys 22m0.411s real 8m40.100s user 587m32.148s sys 21m58.419s real 8m40.084s user 587m25.311s sys 22m2.794s With the patch: real 8m40.351s user 587m21.819s sys 21m57.389s real 8m40.868s user 587m23.730s sys 21m58.737s real 8m40.970s user 587m22.525s sys 22m2.467s I do other builds as well, but that is the biggest, so actually looks ok. -- Cheers, Stephen Rothwell
