Introduce virt_to_phys() virt_to_phys() returns the physical address given a virtual. In most cases this will be just the input value as the vast majority of systems run in a 1:1 mode. However in systems that are not running this way it should report the physical address or ~0 if no mapping exists for the given virtual address. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
