Initial snapshot of work to eliminate 64K MAXPHYS. Basically works for physio (I/O to raw devices); needs more doing to get it going with the filesystems, but it shouldn't damage data. All work's been done on amd64 so far. Not hard to add support to other ports. If others want to pitch in, one very helpful thing would be to sort out when and how IDE disks can do 128K or larger transfers, and adjust the various PCI IDE (or at least ahcisata) drivers and wd.c accordingly -- it would make testing much easier. Another very helpful thing would be to implement a smart minphys() for RAIDframe along the lines detailed in the MAXPHYS-NOTES file.
