+# NUMA is optimized for multi-socket motherboards. A single multi-core CPU can
+# actually run slower with NUMA enabled. Most users will want to set this option
+# to enabled ... in other words, do not use NUMA on a single CPU system.

+# 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!
