/dev/mem: use phys_addr_t for physical addresses
This patch fixes the /dev/mem driver to use phys_addr_t for physical addresses. This is required on PAE systems, especially those that run entirely out of >4G physical memory space. Signed-off-by: Cyril Chemparathy <cyril@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
