mm: fix overflow in vm_map_ram()
When remapping pages accounting for 4G or more memory space, the
operation 'count << PAGE_SHIFT' overflows as it is performed on an
integer. Solution: cast before doing the bitshift.
[[email protected]: fix vm_unmap_ram() also]
[[email protected]: fix vmap() as well, per Guillermo]
