oops/warning report for the week of November 26, 2008

[Arjan van de Ven]

In collecting this report, oopses and warnings with versions prior to 2.6.27 are ignored.
This week, a total of 5450 oopses and warnings have been reported of version 2.6.27+,
compared to 2198 reports in the previous week.

This report is a bit different than the previous weeks; all 2.6.26 and earlier issues are no
longer used, which means the top 12 has shuffled quite a bit, with some new star appearances.

Also I've reworked the "are these two backtraces the same" algorithm; the website should now
be presenting a more compact/concise view due to having the backtraces consolidated in a much
more logical (for the human) way.
