This patch series is separated from the previous "Virtio-balloon
Enhancement" series. The new feature, VIRTIO_BALLOON_F_FREE_PAGE_HINT,
implemented by this series enables the virtio-balloon driver to report
hints of guest free pages to the host. It can be used to accelerate live
migration of VMs.
This patch adds support to walk through the free page blocks in the
system and report them via a callback function. Some page blocks may
leave the free list after zone->lock is released, so it is the caller's
responsibility to either detect or prevent the use of such pages.

ion_page_pool_alloc_pages calls alloc_pages to allocate pages for page
pools. If alloc_pages return NULL, it will return NULL, or it will
return the pages allocate from alloc_pages. So we can just return
alloc_pages without any judgement.

Andy,
I tested your review branch on XPS 9365 which uses power button through
intel-vbtn. I confirmed it worked properly both with usage in OS and during

Because it's fine if it's a memory location too. "cmp" takes pretty
