-# Routine Description:
-# This allows the caller to switch the stack and goes to the new entry point
-#
-# Arguments:
-# EntryPoint - Pointer to the location to enter // rcx
-# Parameter - Parameter to pass in // rdx
-# NewStack - New Location of the stack // r8
-# NewBsp - New BSP // r9 - not used
-#
-# Returns:
-# Nothing. Goes to the Entry Point passing in the new parameters
-#
