gcc (Ubuntu/Linaro 4.8.2-19ubuntu1) 4.8.2

ming@ming:~/ming/linux$
ming@ming:~/ming/linux$ vim block/blk-mq.c
ming@ming:~/ming/linux$ ./build
CHK include/config/kernel.release
CHK include/generated/uapi/linux/version.h
CHK include/generated/utsrelease.h
CALL scripts/checksyscalls.sh
CHK include/generated/compile.h
CC block/blk-mq.o
CHK kernel/config_data.h
LD block/built-in.o
LINK vmlinux
