Peter Anvin <hpa@xxxxxxxxxxxxxxx> CommitDate: Tue, 10 Sep 2013 08:48:40 -0700 reboot: Re-enable the function of variable reboot_default Commit 1b3a5d02ee070c (reboot: move arch/x86 reboot= handling to generic kernel) did some cleanup for reboot= command line, but it made the reboot_default to be invalidated. The default value of variable reboot_default should be 1, and if command line reboot= is not set, system will use the default reboot mode.
