From: Randy Dunlap <rdunlap@infradead.org>
It seems that <linux/interrupt.h> does not need <linux/linkage.h> nor <linux/preempt.h>. 8 kernels builds are successful without these 2 headers (allmodconfig, allyesconfig, allnoconfig, and tinyconfig on both i386 and x86_64).
<linux/interrupt.h> is #included 3875 times in 4.16-rc1, so this reduces #include processing of these 2 files by a total of 7750 times.
Since I only tested x86 builds, this needs to be tested on other $ARCHes as well.

Does anyone know or see why <linux/interrupt.h> needs <linux/linkage.h> or <linux/preempt.h>? There are no direct uses in <linux/interrupt.h> AFAICT.
