in_atomic() has been moved to include/linux/preempt.h, and the filemap.c

With removing hardirq.h, around 32 bytes can be saved for x86_64 bzImage
with allnoconfig.
Wait, what? How would including an unused header file increase the size
of the final image?
Sorry for the wrong message, I double checked again with building kernel
a couple of times then comparing the size, there is no change. Will
remove this from the commit log.
