Linus,

Please pull the "softlockup: print a module list on being stuck" commit
from:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git core-fixes-for-linus

this change is already in the Fedora kernel and it already was useful in
narrowing down sources of soft lockups.

Thanks,

Ingo
