内核信息：Linux student-Lenovo 2.6.35-23-generic-pae #41-Ubuntu SMP Wed Nov 24 10:35:46 UTC 2010 i686 GNU/Linux
下面的程序是实验知道书上的样例，没有问题可言，关键就是我在用 gcc -c file.c -o file.o 时提示没有下面的头文件  
locate linux/kernel.h 发现前5个头文件都在/usr/src/linux-headers-2.6.35-23-generic-pae/include/目录下
最头疼的是第6个头文件asm/processor.h,    locate了一下，输出：

不知道怎么办了? 这是大三linux 内核设计与分析的实验，有做过的人麻烦指点下，最好不要谈什么升级版本什么的，在实验室升级了下次也不能用。

“gcc -c file.c -o file.o 时提示没有下面的头文件 locate linux/kernel.h”
很显然，你没有给gcc指定头文件的路径： “-I/usr/src/linux-headers-2.6.35-23-generic-pae/include/”,gcc找不到他们。
你编的是内核文件，在2.6.*下这样编译是不行的，你需要看看内核模块编译方面的资料，写个Makefile，你可以看一下：《LinuxDeviceDrivers3》，有中文版的，你看个开头就明白了。

编译内核模块不恩你个简单的用gcc -c file.c -o file.o

需要按照kbuild的规则来写个Makefile,

楼上说到那个书上有例子，教你怎么编译一个最简单的模块的。
试试这个吧：

# builds the  example kernel modules;

# then to use one (as root):  insmod 

# If KERNELRELEASE is defined, we've been invoked from the



# kernel build system and can use its language.



ifneq ($(KERNELRELEASE),)

obj-m += file.o



# Otherwise we were called directly from the command



# line; invoke the kernel build system.



else



    KERNELDIR ?= /lib/modules/$(shell uname -r)/build



    PWD := $(shell pwd)



default:

	$(MAKE) -C $(KERNELDIR) M=$(PWD) modules



endif
