# PATCHES #
# TAKEN FROM SOME PARTS OF DIEGUEN89 PKGBUILD
#https://github.com/dieghen89/kernel-netbook/blob/master/PKGBUILD
TUX_ON_ICE="n"
BROADCOM_WL="n"
UKSM="y"
LOCALMODCONFIG="n"
GCONFIG="n"
INSTALL="n"

### HOW-TO:
#
## >> Details for: TUX_ON_ICE
# Set it to "No" you you do not want the Tux On Ice support
#
## >> Details for: BROADCOM_WL
# September is to "and" if you need the iw module for your wireless card
#
#
# P. S. this supports the graysky's PKGBUILD modprobe_db package
#
#
## >> Details for: UKSM
# Set it to "and" to enable the testing uKSM patch, you more info here:
# Http://kerneldedup.org
#
## >> The previous BFQ_IO_SCHEDULER is useless, read the wiki page in google code
