The CONFIG_PREEMPTION change came as a regression fix after rc1 into Linus
tree. The initial plan was to rename PREEMPT to PREEMPT_LL and select
PREEMPT from both PREEMPT_RT and PREEMPT_LL. But that broke (old)defconfig
and such. So it got fixed post rc1.

If you don't want to merge rc2 into your tree, let me know and I'll pick it
up.
