[ARM] Convert pmd_page() to be highmem safe
In the long run, we may want to place page tables in highmem. However, pmd_page() has traditionally been coded to convert the physical address to a virtual one, which won't work with highmem pages. Instead, translate the physical address to a PFN, and then convert the PFN to a struct page instead. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
