+# 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)
