git-apply is for applying plain patches while git-am is for patches from mailboxes.

I would suggest to always use git-am after fetching patches using "b4 am <MSGID>"
from the kernel mailing list.

Please note that when you apply patches with git-am, you should always use the "-s"
option so that the patches are automatically signed-off with your own email address.

Btw, can you push your tree somewhere until you've got your kernel.org account?

Thanks,
Adrian
