Right now bus_addr_t and vm_paddr_t are always aliased to the same underlying integer type on x86, which makes the interchange hard to detect. Shortly, i386 kernel would use uint64_t for vm_paddr_t to enable automatic use of PAE paging structures if hardware allows it, while bus_addr_t would be extended to 64bit only when PAE option is specified. Fix all places that were identified as using bus_addr_t while page address was assumed. This was performed by testing the complete PAE merging patch on machine with > 4G of RAM enabled.
