+Subject: [PATCH] [efi] Ensure drivers are disconnected when ExitBootServices()
+ is called
+
+We hook the UEFI ExitBootServices() event and use it to trigger a call
+to shutdown_boot().  This does not automatically cause drivers to be
+disconnected from their devices, since device enumeration is now
+handled by the UEFI core rather than by iPXE.  (Under the old and
+dubiously compatible device model, iPXE used to perform its own device
+enumeration and so the call to shutdown_boot() would indeed have
+caused drivers to be disconnected.)
+
+Fix by replicating parts of the dummy "EFI root device" from
+efiprefix.c to efidrvprefix.c, so that the call to shutdown_boot()
+will call efi_driver_disconnect_all().
