Use fakeroot instead of sudo, please. I typed that out of head .... and forgot that.

I updated the howto for rc5. If you already have build, do:
git fetch origin
git clean -xfd
git checkout -b v4.3-rc5-passthrough origin/v4.3-rc5-passthrough

And then continue with
cp /boot/config-`uname -r` .config
make oldconfig (Press return until finished)
sudo apt-get install fakeroot kernel-package
make-kpkg --append-to-version "-passthrough" -j4 --initrd linux-headers linux-image

I have completed the above commands successfully, but when I run uname –r I get the following :
root@htpc:~/linux# uname -r
4.3.0-040300rc4-generic

After compiling you need to install the resulting .deb files from ../ with sudo dpkg -i
