How can I change cr0 register in redhat system

[Fan Yang <lljyangfan@xxxxxxxxx>]

hi all:

       when I change the cr0 register I get a "Segmentation fault (core dumped)".

       my code is :

       

.data

.text

.global _start

_start:

        movl %eax, %cr0

      this code can work well in ubuntu system when I use root to run it. So what can I do to work it in redhat system?

     thanks
