Subject: [PATCH] kmemcheck: move hook into __alloc_pages_nodemask() for the
 page allocator

Now kmemcheck_pagealloc_alloc() is only called by __alloc_pages_slowpath().
__alloc_pages_nodemask()
	__alloc_pages_slowpath()
		kmemcheck_pagealloc_alloc()

And the page will not be tracked by kmemcheck in the following path.
__alloc_pages_nodemask()
	get_page_from_freelist()

So move kmemcheck_pagealloc_alloc() into __alloc_pages_nodemask(),
like this:
__alloc_pages_nodemask()
	...
	get_page_from_freelist()
	if (!page)
		__alloc_pages_slowpath()
	kmemcheck_pagealloc_alloc()
	...
