sparc32: Fix page_to_phys().
It doesn't account for phys_base like it should, fix by using page_to_pfn(). While we're here, make virt_to_page() use pfn_to_page() as well, so we consistently use the asm/memory-model.h abstractions instead of open-coding memory model assumptions. Tested-by: Kristoffer Glembo <kristoffer@gaisler.com> Signed-off-by: David S. Miller <davem@davemloft.net>
