* There is now a 'busses' folder, and the extant USB/SDHCI/Bluetooth/etc. docs now live in it, instead of various other places. * kernel/ports is now kernel/arch, like it is in src/system. SPARC documentation is now in there, too. * VM files (these are rather outdated) are now in kernel/vm. * SCSI ASC info removed, this is easily available online and it doesn't seem to be very relevant.
