Niestety, linux-uksm w AUR od dość dawna nie jest aktualizowany. Aktualnie (stan na dzień 18 grudnia 2014 roku) - mamy dostępną wersję 3.16.4. Jest to wersja nieco archaiczna - zważywszy na fakt, że aktualna wersja dla linux-uksm to 3.17.7 (patch dla wersji 3.18 jeszcze się nie ukazał). Postanowiłem nieco przerobić PKGBUILD dodając to, czego moim zdaniem w linux-uksm brakuje najbardziej - czyli
https://github.com/graysky2/kernel_gcc_patch. PKGBUILD powinien być teraz nieco bardziej czytelny dzięki bardziej szczegółowym opisom możliwych do zastosowania opcji.

### BUILD OPTIONS
# Set these variables to ANYTHING that is not null to enable them
# 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=
# 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.
_use_current=
# Alternative I/O scheduler by Paolo.
# Set this if you want it enabled globally i.e. for all devices in your system
# If you want it enabled on a device-by-device basis, leave this unset and see:
# https://wiki.archlinux.org/index.php/Linux-ck#How_to_Enable_the_BFQ_I.2FO_Scheduler
