<linux/fs.h>, <linux/mm.h>, <linux/sched.h>, <linux/pagemap.h>
are usually the main culprits. Each of these suckers pulls in
dozens and dozens of includes.

So every time someone wants for eg, something trivial like
jiffies, they end up pulling in crap like <asm/mmx.h>
It's hurrendous how much stuff we have in some of the above
mentioned files which probably deserves their own files.

Updated graphs of these dependancies just went up to
ftp://ftp.kernel.org/pub/linux/kernel/people/davej/misc/graphs/

(old versions are in the parent dir before/after the last crapectomy)
