3.7-stable review patch. If anyone has any objections, please let me know.
------------------ From: David Woodhouse <[email protected]> commit f791620fa7517e1045742c475a7f005db9a634b8 upstream. If the bootloader calls the EFI handover entry point as a standard function call, then it'll have a return address on the stack. We need to pop that before calling efi_main(), or the arguments will all be out of position on the stack.
