There is actually a PPA with pre-patched BFQ kernels for Trusty Tahr (14.04.2) its located here but it is kernel 3.16 and i believe your looking for something more recent like 3.19 or 4.1 with bfq... i suggest you try to google on how to compile a custom kernel for ubuntu =)) so that you can maybe get pf-kernel work on ubuntu... but if you want the 3.16-bfq here are the.....
Terminal Commands for adding the bfq kernel ppa's
sudo add-apt-repository ppa:nick-athens30/trusty-bfq
sudo apt-get update
sudo apt-get install linux-image-generic-bfq linux-headers-generic-bfq
and if you have a later a kernel, say 3.19 ... you can easily change the default kernel grub boots into (if you want to boot to 3.16-bfq) using grub customizer which can be installed by
sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer
