The flag actually needs a recent gcc 4.3 snapshot (it's a new feature the gcc developers added especially for the kernel :), so if this didn't work it would fail on the vast majority of systems. Somehow it doesn't? At least here it compiles fine. I notice the final comma is missing, Mel does it work when you change the line to cflags-y += $(call cc-option,-mpreferred-stack-boundary=3,) If not please run gcc -O2 -mpreferred-stack-boundary=2 -S -xc /dev/null -o x.o echo $?
