There was an issue with kmemleak, I fixed it here:

Mike, please run this with kmemleak enabled and running, and also try to get

page_to_pfn is usually implemented by pointer arithmetics on the memory
map, which means that bogus input can lead to even more bogus output.
Powerpc had a pfn_valid check on the regult to it's page_to_phys
implementation when CONFIG_DEBUG_VIRTUAL is defined, which seems
generally useful, so add t
page_to_phys is duplicated by all architectures, and from some strange
reason placed in where it doesn't fit at all.
phys_to_page is only provided by a few architectures despite having a lot
of open coded users.
Provide generic versions in to make these
helpers more easily usable.

arm64 can support multiple base page sizes. Instead of selecting a page
size at compile time, as is done today, we will make it possible to
select the desired page size on the command line.
In this case PAGE_SHIFT and it's derivatives, PAGE_SIZE and PAGE_MASK
