Subject: linux-next: manual merge of the lost-spurious-irq tree with the tip
 tree

Hi Tejun,

Today's linux-next merge of the lost-spurious-irq tree got a conflict in
kernel/irq/internals.h between commits
a77c4635915021c646cc017f22239e66d1aab4d5 ("genirq: Add new functions to
dummy chips") and bd151412263a67b5321e9dd1d5b4bf6d96fdebf3 ("genirq:
Provide config option to disable deprecated code") from the tip tree and
commits 32b5d378f49485f3ae172eb0ac2bfc4ebbbdb060 ("irq: cleanup
irqfixup") and 80f97e2b33c3e66c11b10abd2890506a3abeb320 ("irq: make
spurious poll timer per desc") from the lost-spurious-irq tree.

Just context changes.  I fixed it up (see below) and can carry the fixes
as necessary.
