Subject: linux/preempt.h needs linux/thread_info.h
From: Horms <horms@xxxxxxxxxxxx>
It seems that linux/preempt.h needs to include linux/thread_info.h in order
to access current_thread_info(), which is used in preempt_count().
I guess that all callers of preempt_count() must include both
linux/thread_info.h and linux/preempt.h directly or indirectly, as this
does not cause a compile error. I noticed the problem while working on an
unrelated issue in xen-land.
