IMHO the
BUG_ON(vma->vm_flags & VM_PFNMAP);
in vm_insert_page should just become a WARN_ON_ONCE with an error
return, and then we just need to gradually fix up the callers that
trigger it instead of coming up with workarounds like this.

Currently system heap maps its buffers with VM_PFNMAP flag using
remap_pfn_range. This results in such buffers not being accounted
for in PSS calculations because vm treats this memory as having no
page structs. Without page structs there are no counters representing
how many processes are mapping
