git updates and patches for 2.6.30-rc2

[mort at sgi.com (Martin Hicks)]

I think I've caught up with the code flux on x86_64 for the 2.6.30
release.  Backtraces seem to be working fairly reliably again on x86_64.

Git and patches available in the usual places:

git://oss.sgi.com/kdb/kdb.git

ftp://oss.sgi.com/projects/kdb/download/v4.4/
