Peter Zijlstra 6edaf68a87 [PATCH] mm: arch do_page_fault() vs in_atomic()
In light of the recent pagefault and filemap_copy_from_user work I've gone
through all the arch pagefault handlers to make sure the inc_preempt_count()
'feature' works as expected.

Several sections of code (including the new filemap_copy_from_user) rely on
the fact that faults do not take locks under increased preempt count.
