This causes my 64-cpu Niagara2 box to completely hang when I run "make
clean" on a kernel tree after a fresh bootup.
Can we just revert all of this broken code until it's sorted out? :-/
We're going on 4 days with unfixed major regressions from the
scheduler tree merge, and these regressions make systems unusable.
This is blocking my own work, and I'm starting to lose my patience.
