Our automated test suite looks for keywords like error, fail, warning in the
boot log. In the case when the nmi watchdog is determined to be stuck in
check_nmi_watchdog(), none of those keywords are displayed.
This patch adds a keyword, 'Warning, so it makes it easier to notice when the
nmi
watchdog isn't working correctly.
No technical changes have been made. Compiler tested.
