But doing the phys_to_page() before the read seems reasonable.
Although, it may not make a difference at all. On the system
above, all of the pages in the node have page structures
associated with them, even with SPARSEMEM_EX, so it doesn't
make a difference. And if I search just the unity-map region,
the CRASHDEBUG(1) output is identical with respect to the
number of pages read vs. checked.
