### PATCH AND BUILD OPTIONS
# Set these variables to ANYTHING that is not null (y or hello or 2 or "I like icecream") to enable them
#
_makenconfig=   # Tweak kernel options prior to a build via nconfig
_localmodcfg=   # Compile ONLY probed modules
_use_current=   # Use the current kernel's .config file
_BFQ_enable_=  # Enable BFQ as the default I/O scheduler
_NUMAdisable=y  # Disable NUMA in kernel config

### DOCS
# This package has shipped with GCC optimisations since the 3.6.9-3 release, currently with enable_additional_cpu_optimizations_for_gcc.patch.
# This allows users an expanded scope of CPU specific options.
# Consult the following resources to understand which option is right for you application:
#
# http://en.gentoo-wiki.com/wiki/Safe_Cflags/Intel
# http://en.gentoo-wiki.com/wiki/Safe_Cflags/AMD
# http://www.linuxforge.net/docs/linux/linux-gcc.php
# http://gcc.gnu.org/onlinedocs/gcc/i386-and-x86_002d64-Options.html

# DETAILS FOR _localmodcfg=
# 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 - make CERTAIN that all modules are modprobed BEFORE you begin making the pkg!
#
# To keep track of which modules are needed for your specific system/hardware, give my module_db script
# a try: https://aur.archlinux.org/packages/modprobed-db/  Note that if you use my script, this PKGBUILD
# will auto run the 'sudo modprobed_db reload' for you to probe all the modules you have logged!
#
# More at this wiki page ---> https://wiki.archlinux.org/index.php/Modprobed_db

# DETAILS FOR _use_current=
# 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.

# DETAILS FOR _BFQ_enable=
# Alternative I/O scheduler by Paolo.  For more, see: http://algo.ing.unimo.it/people/paolo/disk_sched/

# DETAILS FOR _NUMAdisable=
# Since >99 % of users do not have multiple CPUs but do have multiple cores in one CPU.
# see, https://bugs.archlinux.org/task/31187
