rGac4b43b7b9dd: LinuxKPI: prefer struct page [*] over struct vm_page[_t]
Summary

LinuxKPI is based on Linux 'struct page' which is currently aliased
to struct vm_page. Upcoming changes may change that so start using
'struct page *' instead vm_page_t to make future changes transparent.

This is a continuation of 9e9c682ff3a1 and should be a NOP.
