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()
...
