Subject[RFC PATCH 08/30] softirq: Move vectors bits to bottom_half.h
Date
From: Frederic Weisbecker <fweisbec@gmail.com>

Using the bottom-half masking APIs defined in linux/bottom-half.h won't
be possible without passing the relevant softirq vectors that are
currently defined in linux/interrupt.h

Yet we can't include linux/interrupt.h from linux/bottom-half.h due to
circular dependencies.

Now the vector bits belong to bottom halves anyway, so moving them there
is more natural and avoid nasty header dances.
