Kernel module packages compiling is not cached (e.g. mac80211) even with CONFIG_CCACHE on. CC should be set to KERNEL_CC in KERNEL_MAKE_FLAGS at kernel.mk to allow kernel module packages using ccache. Signed-off-by: Zeyu Dong <dzy201415@gmail.com> --- The package Makefile is not sourcing kernel-defaults.mk, where CC is set to KERNEL_CC, which will be ccache when CONFIG_CCACHE is on. Also, some module packages are using KERNEL_MAKE_FLAGS instead of standard KERNEL_MAKE to compile. --- include/kernel-defaults.mk | 4 ---- include/kernel.mk | 4 ++++ 2 files changed, 4 insertions(+), 4 deletions(-)
