    linuxkpi: Add macros for might_lock_nested() and lockdep_(re/un/)pin_lock()
    
    In Linux, these are macros to locks in the kernel for scheduling purposes.
    But as with other macros in this header, we aren't doing anything with them
    so we are doing `do {} while (0)` for now.
    
    This is needed by the drm-kmod 5.7 update.
