Currently the page poisoning setting wasn't being enabled unless free page
hinting was enabled. However we will need the page poisoning tracking logic
as well for unused page reporting. As such pull it out and make it a
separate bit of config in the probe function.

Add support for the page reporting feature provided by virtio-balloon.
Reporting differs from the regular balloon functionality in that is is
much less durable than a standard memory balloon. Instead of creating a
list of pages that cannot be accessed the pages are only

Move the head/tail adding logic out of the shuffle code and into the
__free_one_page function since ultimately that is where it is really
needed anyway. By doing this we should be able to reduce the overhead
and can consolidate all of the list addition bits in one spot.

In order to support page reporting it will be necessary to store and
retrieve the migratetype of a page. To enable that I am moving the set and
get operations for pcppage_migratetype into the mm/internal.h header so
that they can be used outside of the page_alloc.c file.

Move the static definition for things such as HUGETLB_PAGE_ORDER out of
asm/pgtable.h and place it in page-defs.h. By doing this the includes
become much easier to deal with as currently arm64 is the only architecture
that didn't include this definition in the asm/page.h

Change the logic used to generate randomness in the suffle path so that we
can avoid cache line bouncing. The previous logic was sharing the offset
and entropy word between all CPUs. As such this can result in cache line
bouncing and will ultimately hurt performance when
Sorry about that. Looks like I fat fingered things and copied the
command line into the cover page. I corrected the subject here, and
pulled the command line out of the message below.

In order to pave the way for free page reporting in virtualized
environments we will need a way to get pages out of the free lists and
identify those pages after they have been returned. To accomplish this,
this patch adds the concept of a Reported Buddy, which is
