1. 在 LINUX 3.5源代码目录下执行 yum install ncurses-devel make menuconfig
2 打开内核跟踪事件，用于SYSTEMTAP跟踪
kernel hacking --->tracers(new)--->enable uprobes-based dynamic events
文件系统相关选项要打开
即为
CONFIG_SYSFS_DEPRECATED_V2=y
不这样设为出错，安装内核重起后就会出现如下状况
mount: could not find filesystem ‘/dev/root’
setuproot: moving /dev failed: No such file or directory
setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys: No such file or directory
switchroot: mount failed: No such file or directory
3. 头文件出错

[root@localhost linux-3.5]# cp include/linux/hid.h /usr/include/linux/
vi samples/hidraw/hid-example.c
将13-15行的如下3行移动到33行以后。

4.确定参数设置 .config
[root@localhost linux-3.5]# cat .config | grep CONFIG_DEBUG_INFO
CONFIG_DEBUG_INFO=y
[root@localhost linux-3.5]# cat .config | grep CONFIG_KPROBES
CONFIG_KPROBES=y
[root@localhost linux-3.5]# cat .config | grep CONFIG_RELAY
CONFIG_RELAY=y
[root@localhost linux-3.5]# cat .config | grep CONFIG_DEBUG_FS
CONFIG_DEBUG_FS=y
[root@localhost linux-3.5]# cat .config | grep CONFIG_MODULES
CONFIG_MODULES=y
[root@localhost linux-3.5]# cat .config | grep CONFIG_MODULE_UNLOAD
CONFIG_MODULE_UNLOAD=y
[root@localhost linux-3.5]#cat .config | grep CONFIG_UTRACE (linux 3.5 没有这个选项）
CONFIG_UTRACE=y
[root@localhost linux-3.5]#cat .config | grep CONFIG_SYSFS_DEPRECATED_V2
CONFIG_SYSFS_DEPRECATED_V2=y
5.make CONFIG_DEBUG_SECTION_MISMATCH=y 编绎内核
故障问题：
编译内核时出现“make CONFIG_DEBUG_SECTION_MISMATCH=y” 错误提示：
root@localhost linux-3.5]#make modules
CHK include/linux/version.h
CHK include/generated/utsrelease.h
CALL scripts/checksyscalls.sh
Building modules, stage 2.
MODPOST 1106 modules
WARNING: modpost: Found 2 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'
排错记录：
编辑.config文件，加入：CONFIG_DEBUG_SECTION_MISMATCH=y重新编译，还是出错，于是直接
make CONFIG_DEBUG_SECTION_MISMATCH=y编译成功。
root@localhost linux-3.5]#make CONFIG_DEBUG_SECTION_MISMATCH=y
6.make modules_install
7.make install
8.make headers_install
