This is a non-critical patch, that makes configuring an rt kernel a

little nicer.

Comments are welcome of course.


Signed-off-by: John Kacur <jkacur at gmail dot com>


This patch makes the following changes.

1. Hides the visibility of PREEMPT_SOFTIRQS and PREEMPT_HARDIRQS if PREEMPT_RT

(Complete Preemption) is choosen, since these values are then set (selected) to

be "y".


2. Changes the PREEMPT_HARDIRQS to depend on PREEMPT_SOFTIRQS instead of

forcing PREEMPT_SOFTIRQS to y if PREEMPT_HARDIRQS is choosen. (this is somewhat

an abuse of select)


3. Minor spelling fix. (tat to that)

Hi John,


Thanks, but instead of this:


 depends on PREEMPT_RT != y


could you do:


 depends on !PREEMPT_RT
