补充：make modules SUBDIRS=指定编译那个目录下的Makefile
今天在编译linux kernel的时候发现make menuconfig中配置成<M>模式的驱动模块没有加入编译之,下面命令编译内核的：
make uImage
通过查看kernel的makefile发些了一些蛛丝马迹，现在将工作笔记记录如下：在linux kernel下运行终端，输入如下命令查看kernel编译相关的一些信息
make help

gtags - Generate GNU GLOBAL index
kernelrelease - Output the release version string
kernelversion - Output the version stored in Makefile
headers_install - Install sanitised kernel headers to INSTALL_HDR_PATH
(default: /home/book/workspace/kernel/linux-3.4.2_jz2440/usr)
Static analysers
checkstack - Generate a list of stack hogs
namespacecheck - Name space analysis on compiled kernel
versioncheck - Sanity check on version.h usage
includecheck - Check for duplicate included header files

htmldocs - HTML
pdfdocs - PDF
psdocs - Postscript
xmldocs - XML DocBook
mandocs - man pages
installmandocs - install man pages generated by mandocs
cleandocs - clean all generated DocBook files
Architecture specific targets (arm):
* zImage - Compressed kernel image (arch/arm/boot/zImage)
Image - Uncompressed kernel image (arch/arm/boot/Image)
* xipImage - XIP kernel image, if configured (arch/arm/boot/xipImage)
uImage - U-Boot wrapped zImage
bootpImage - Combined zImage and initial RAM disk
(supply initrd image via make variable INITRD=<path>)
dtbs - Build device tree blobs for enabled boards
install - Install uncompressed kernel

Install using (your) ~/bin/installkernel or
(distribution) /sbin/installkernel or
install to $(INSTALL_PATH) and run lilo
发现并没有把make menuconfig中配置成<M>模式的驱动模块没有加入编译，分析才发现还得执行如下命令就OK了。
make modules
相关的*.ko驱动模块就在kernel目录下!
