[patch 7/9] Guest page hinting: minor fault optimization.
...call
to page_cache_release. In general that causes an unnecessary page state
transition from volatile to volatile. Not what we want. To get rid of
these state transitions as well special variants of put_page_testzero/
page_cache_release are introduced that do not attempt to make the page
volatile. page_cache_release_nocheck is then used in free_page_and_swap_cache
and release_pages. This makes the unmap of ptes state transitions free.

hook and architecture specific code.
