Hello,

Top-posting is frowned upon in the Linux Kernel mailing lists. Please
use the interleaved style instead, as described in this Wikipedia

To add to what Greg said, disabling the staging drivers config option
in the .config file speeds up the entire process. To do this, just
comment out the CONFIG_STAGING line in that file.
