I can't compile atomic.h in Ubuntu 9.4, below is source code:

#include
#include

#include

int main(void) {
puts("!!!Hello World!!!");
return EXIT_SUCCESS;
}

the following is the error info:
/usr/src/linux-headers-2.6.28-11/arch/x86/include/asm/alternative.h:45: 错误： expected specifier-qualifier-list before ‘u8'

Kernel code has no main() function. Please do some reading on kernel module development before you try to mung your system...
