[PATCH -rt 2/9] Dont allow non-threaded softirqs and threaded hardirqs

[Daniel Walker]

From: Steven Rostedt <rostedt@xxxxxxxxxxx>

Ingo,

I think this was sent before, and it did cause problems before. Would
there be *any* reason to have non-threaded softirqs but threaded hardirqs.
I can see lots of issues with that.

This patch has selecting hardirqs also select softirqs as threads.

 	  This option reduces the latency of the kernel by 'threading'
           hardirqs. This means that all (or selected) hardirqs will run
