(instead of size_t) to avoid possible overflow when system may have more than 4GB of memory (like PAE). The behavior of rbus_min_start_hint() remains the same. While here, fix printf's format strings (paddr_t => PRIxPADDR). Use ctob() and cast physmem to psize_t to avoid losing bits above 4GB. Comes from PAE patch from Jeremy Morse; adaptation by me. Compile tested for GENERIC only. No regression expected.
