* Name: up_pthread_start
*
* Description:
* In this kernel mode build, this function will be called to execute a
* pthread in user-space. When the pthread is first started, a kernel-mode
* stub will first run to perform some housekeeping functions. This
* kernel-mode stub will then be called transfer control to the user-mode
* pthread.
*
* Normally the a user-mode start-up stub will also execute before the
* pthread actually starts. See libc/pthread/pthread_startup.c
*
* Input Parameters:
* entrypt - The user-space address of the pthread entry point
* arg - Standard argument for the pthread entry point
*
* Returned Value:
* This function should not return. It should call the user-mode start-up
* stub and that stub should call pthread_exit if/when the user pthread
* terminates.
