commit 97709069 upstream. ARC kernels have historically been built with -O3, despite top level Makefile defaulting to -O2. This was facilitated by implicitly ordering of arch makefile include AFTER top level assigned -O2. An upstream fix to top level a1c48bb1 ("Makefile: Fix unrecognized cross-compiler command line options") changed the ordering, making ARC -O3 defunct. Fix that by NOT relying on any ordering whatsoever and use the proper arch override facility now present in kbuild (ARCH_*FLAGS) Depends-on: ("kbuild: Allow arch Makefiles to override {cpp,ld,c}flags") Suggested-by: Michal Marek <mmarek@suse.cz> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Signed-off-by: Kamal Mostafa <kamal@canonical.com>
