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.

This patch makes SPARC targets build again. It is caused by
phys_addr_t and phys_size_t being defined in the wrong header
file. include/lmb.h need those typedefs to build.
