1. When I try to build the kernel I get an error telling me to run "make mrproper"

Generally, running "git clean -f -d" to delete all files not in the git repository is good enough to start a new build. However, this command does not clean files ignored by the git repository. Some of these files conflict with the linux build scripts. The best way to resolve this situation is to run "make mrproper", then check "git status" to ensure everything looks right, and then finally being the build again.
