Add initial support for the FreeBSD/alpha kernel. This is very much a work in progress and has never booted a real machine. Initial development and testing was done using SimOS (see http://simos.stanford.edu for details). On the SimOS simulator, this port successfully reaches single-user mode and has been tested with loads as high as one copy of /bin/ls :-). Obtained from: partly from NetBSD/alpha

Add new functions fill_fpregs() and set_fpregs(), like fill_regs() and set_regs() but for the floating point register state. The code is stolen from procfs_machdep.c, and moved out of there into machdep.c. These functions are needed for generating ELF core dumps.

#ifdef _SYS_BUS_H_
Update the ata driver to take more advantage of newbus, this was needed to make attach/detach of devices work, which is needed for the PCCARD support. (PCCARD support is still not working though, more to come on that) Support the CMD646 chip which is used on many alphas, sadly only in WDMA2 mode, as the silicon is broken beyond belief for UDMA modes. Lots of cosmetic fixes here and there. Sorry for the size of this megapatchfromhell but it was not possible otherwise... newbus patches based on work from: dfr (Doug Rabson)

Handle PCI devices that actually use an ISA IRQ for the cia and tsunami chipsets. An example of this is the USB controller on these chipsets. With this, I can now use USB devices on the test Alpha I am borrowing at the moment. Reviewed by: dfr, obrien
