Wersja dla kernela 4.2. Poniższy PKGBUILD jest skonstruowany nieco inaczej, a mianowicie nakłada patch gc (który jest obecnie wyłącznie przystosowanym BFS dla kernela 4.2) na waniliowe źródła kernela. Dodatkowo nakładane są patche BFQ (jeszcze dla linii 4.1, ale pracuje bez problemu) oraz patch graysky'ego w oryginalnej wersji. Nie trzeba zatem stosować opcji "native" dla procesorów Intel.

### BUILD OPTIONS
# Set these variables to ANYTHING that is not null to enable them
# Tweak kernel options prior to a build via nconfig
_makenconfig=
# Tweak kernel options prior to a build via menuconfig
_makemenuconfig=
# Tweak kernel options prior to a build via xconfig
_makexconfig=y
# Tweak kernel options prior to a build via gconfig
_makegconfig=
# NUMA is optimized for multi-socket motherboards.
# A single multi-core CPU actually runs slower with NUMA enabled.
# See, https://bugs.archlinux.org/task/31187
_NUMAdisable=y
# Compile ONLY probed modules
# As of mainline 2.6.32, running with this option will only build the modules
# that you currently have probed in your system VASTLY reducing the number of
# modules built and the build time to do it.
#
# WARNING - ALL modules must be probed BEFORE you begin making the pkg!
#
# To keep track of which modules are needed for your specific system/hardware,
# give module_db script a try: https://aur.archlinux.org/packages/modprobed-db
# This PKGBUILD will call it directly to probe all the modules you have logged!
#
# More at this wiki page ---> https://wiki.archlinux.org/index.php/Modprobed_db
_localmodcfg=y
# Use the current kernel's .config file
# Enabling this option will use the .config of the RUNNING kernel rather than
# the ARCH defaults. Useful when the package gets updated and you already went
# through the trouble of customizing your config options. NOT recommended when
# a new kernel is released, but again, convenient for package bumps.
