Subject: ipmi: Fix watchdog NMI handling
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=6af94767daf6364dcc74d70f494fe0dda795824f;p=people%2Fpauldu%2Fqemu.git

ipmi: Fix watchdog NMI handling

The wrong logic was used for detection (so it wouldn't work at all)
and the wrong interface was used to inject the NMI if the detection
logic was correct.
