# APKBUILD based on linux-vanilla aport. Changes:
# - disabled module installation
# - add !check !tracedeps
# - package: just install zimage and kernel.release, because the kernel config
#	does not generate modules or dtb files
# - do not create -dev subpackage (makes no sense without module support)
#
# Kernel config based on: arch/arm/configs/cyanogenmod_n7100_defconfig
# Changes:
# - enable devtmpfs (needed for udev -> touch support in weston)
# Patches:
# extdsp_inline.patch: Fix for extern and inline errors on compile
# fimc_lite.patch: Fix for inline error
# timeconst_fix.patch: Removed condition for depricated feature in Perl (bug present in Linux 3.9 and under)
