6.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Helge Deller <deller@xxxxxx> commit 6472036581f947109b20664121db1d143e916f0b upstream. Make sure to start the kthread to check the power button on qemu as well if the power button address was provided. This fixes the qemu built-in system_powerdown runtime command.
