For patches 1-9:

Tested-by: Nathan Chancellor <nathan@kernel.org> # build only

Prior to this series:

    [INFO] Memory used: 25.09GB

After this series:

    [INFO] Memory used: 19.27GB

Our builds on TuxSuite were consistenly timing out after four hours and
they had no problem passing with this series (the worst time was 2.2h,
which is line with the VM specs that they use I believe):

Thanks a lot!
