Subject: Allow shutdown code SHUTDOWN_HALT, which we handle here in exactly the same
X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~16763^2~26
X-Git-Url: https://dgit.raspbian.org/%22http:/www.example.com/cgi/%22https://%22%22/%22http:/www.example.com/cgi/%22https:/%22%22?a=commitdiff_plain;h=10956b773945319f50f76beedf801cb0739457ff;p=xen.git

Allow shutdown code SHUTDOWN_HALT, which we handle here in exactly the same
way as POWEROFF.  The tools use the distinction when the code is returned.
