what will kernel_execve() does..?

Hi All I m having a doubt about.. what kernel_execve() does...? As per the comment it should make the kernel thread a user space process. I am doing a kernel bringup. while launching the init process, i was struck in this function... kernel_execve() in arch./arm/kernel/sys_arm.c I am feeling i was struck in some kind of infinite loop here..and program control is not reaching till user space init process's main function. *Can someone tell me, is there any condition that i am missing here, failing which the kernel will struck in infinite loop and doesnt switch to user space?* -- With regards, Sandeep Kumar Anantapalli,
