This patch implements simple getter interface for syscall user dispatch configuration info.

+A thread can fetch the current Syscall User Dispatch configuration with the following prctl:

This should have been ended with double colon (::) to make below code code block, to be consistent with syscall_user_dispatch definition below.

• prctl(PR_GET_SYSCALL_USER_DISPATCH, <dispatch_config>))

+<dispatch_config> is a pointer to a ``struct syscall_user_dispatch`` as defined in ``linux/include/linux/syscall_user_dispatch.h``::

• struct syscall_user_dispatch {

•    char __user *selector;
  

•    unsigned long offset;
  

•    unsigned long len;
  

•    bool    on_dispatch;
  

• };

Thanks.
