?说明
0 android4.7z.001 通过7zip将此分卷解开，得到一个android4文件，然后改名成android4.tar.gz
1 把文件名后面的gzip后缀去掉，这不是一个压缩文件
2 在源码下建立kernel目录
3 解压kernel.tar，然后把内容拷贝到源码的kernel目录中。
4 要看kernel的内容的话，必须进入msm或common或goldfish下，通过git branch -avl查看分支
然后通过git branch xxx remote分支来释放代码
//ztg add
//通过git branch -r或-a查询，选项r只能查远程版本，选项a会把本地和远程的版本都列出
[root@localhost common]# git branch -a

在交叉编译或编译Linux内核的时候需要把，内核或内核的模块安装到指定的目录。
可使用命令： make install 和make modules_install 。
同时指定路径分别为，INSTALL_PATH和INSTALL_MOD_PATH。
不过在指定路径的时候可得要注意了，一定要为绝对路径而非相对路径。
----------------------------------
[root@localhost android-3.10]# mkdir out_modules
[root@localhost android-3.10]# pwd
/run/media/root/11fb38b3-24ee-4306-b554-40aaeae1a204/android/Android4.4-with-kernel/kernel/common/android-3.10

----------------------------------
应用安装指定
make install DESTDIR=/home/luther/gliethttp_dir

内核开发基础——make mrproper及mrproper的含义
Linux下面去编译项目之前，一般常会用make mrproper去先删除之前编译所生成的文件和配置文件，备份文件等，其中，mrproper和distclean，clean之间的区别，Linux内核源码根目录下面的makefile中，有很清晰的解释：
help:
@echo 'Cleaning targets:'
@echo ' clean - Remove most generated files but keep the config and'
@echo ' enough build support to build external modules'
@echo ' mrproper - Remove all generated files + config + various backup files'
@echo ' distclean - mrproper + remove editor backup and patch files'

arm-eabi, arm-linux-androideabi, arm-linux-gnueabi, arm-none-linux-gnueabi工具链的区别
链接工具命名方式为：
arch-vendor-os-abi ， 即cpu构架， 供应商， 操作系统， abi类型
例如：
1、arm-none-linux-gnueabi
(ARM architecture, no vendor, linux OS, and the gnueabi ABI)
用于编译ARM架构的u-boot、linux内核、linux应用等
2、arm-none-eabi
用于编译ARM架构的裸机系统(包括linux的 boot、kernel)
3、arm-eabi
Android ARM 编译器
所以标题中提到的工具链表示的含义是：
arm-eabi: (ARM architecture and the EABI)
arm-linux-androideabi: (ARM architecture, linux OS, and the androideabi ABI)
arm-linux-guneabi: (ARM architecture, linux OS, and the gnueabi ABI)
arm-none-linux-gnueabi: (ARM architecture, no vendor, linux OS, and the gnueabi ABI)
工具链的工具通常有：
add2line：将你要找的地址转成文件和行号，它要使用 debug 信息。
ar：产生、修改和解开一个存档文件
as：gnu的汇编器
c++filt：C++ 和 java 中有一种重载函数，所用的重载函数最后会被编译转化成汇编的标，c++filt 就是实现这种反向的转化，根据标号得到函数名
gprof：gnu 汇编器预编译器
ld：gnu 的连接器
nm：列出目标文件的符号和对应的地址
objcopy：将某种格式的目标文件转化成另外格式的目标文件
objdump：显示目标文件的信息
ranlib：为一个存档文件产生一个索引，并将这个索引存入存档文件中
readelf：显示 elf 格式的目标文件的信息
size：显示目标文件各个节的大小和目标文件的大小
strings：打印出目标文件中可以打印的字符串，有个默认的长度，为4
strip：剥掉目标文件的所有的符号信息

------------------解决方法
在内核配置的时候选择上如下内容：
方法一：
make menuconfig
Kernel Features --->
[*] Use the ARM EABI to compile the kernel
[*] Allow old ABI binaries to run with this kernel (EXPERIMENTAL)
方法二：
make -j4 ARCH=arm CROSS_COMPILE=/opt/android-on-linux/android-ndk-r9d/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/bin/arm-linux-androideabi- CONFIG_AEABI=y
参考：http://blog.chinaunix.net/uid-14735472-id-5593127.html

Looks like some kernel config settings are missing (noch sure which ones).
Instead of copying the kernel config do a "make bcmrpi_defconfig" in the cirrus tree. Just tried it here and it worked fine.

默认配置文件：

[root@localhost android-3.10]# ls ./arch/arm/configs/
