Your config has:
# CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE is not set
CONFIG_CC_OPTIMIZE_FOR_SIZE=y
But all our defconfigs use CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE. Which
explains why we didn't catch this in build testing. I've added a build
with OPTIMIZE_FOR_SIZE=y so hopefully we'll catch any similar errors in
future.
cheers
