<red face>

I forgot to move CONFIG_RCU_FAST_NO_HZ from my development tests to my
regression tests.  I have done so now.  I have also added allyesconfig
to my compile tests, which I should have done long ago.

I am testing the fix, and will rebase the stack onto 2.6.34-rc7 when it
comes out.

							Thanx, Paul
