Rebasing is not same as patches application.

Also normal, cherry-picking is not the same as applying a patch series.

I guess so, I have the same problem as Jakub, see below. I had to use 'git am -3' to apply you 
series. As you can see, git falls back to 3 way merge for patch 1, which means your series is close 
to but not fully in sync with net-next.

[root@localhost linux-powerpc]# git remote -v
net-next

net-next        
https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git (push)

[root@localhost linux-powerpc]# git checkout net-next/master -b net-next
Switched to a new branch 'net-next'

When you have resolved this problem, run "git am --continue".
If you prefer to skip this patch, run "git am --skip" instead.
To restore the original branch and stop patching, run "git am --abort".
