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

Support bounce buffers for ISA DMA on the alpha. This is required for the irongate chipset (used in the UP1000) which does not support scatter/gather DMA. We'll still use scatter gather if the core logic chipset supports it. Reviewed by: dfr

Complete rework of the PowerPC pmap and a number of other bits in the early boot sequence. The new pmap.c is based on NetBSD's newer pmap.c (for the mpc6xx processors) which is 70% faster than the older code that the original pmap.c was based on. It has also been based on the framework established by jake's initial sparc64 pmap.c. There is no change to how far the kernel gets (it makes it to the mountroot prompt in psim) but the new pmap code is a lot cleaner. Obtained from: NetBSD (pmap code)

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.

- Overhaul the software interrupt code to use interrupt threads for each type of software interrupt. Roughly, what used to be a bit in spending now maps to a swi thread. Each thread can have multiple handlers, just like a hardware interrupt thread. - Instead of using a bitmask of pending interrupts, we schedule the specific software interrupt thread to run, so spending, NSWI, and the shandlers array are no longer needed. We can now have an arbitrary number of software interrupt threads. When you register a software interrupt thread via sinthand_add(), you get back a struct intrhand that you pass to sched_swi() when you wish to schedule your swi thread to run. - Convert the name of 'struct intrec' to 'struct intrhand' as it is a bit more intuitive. Also, prefix all the members of struct intrhand with 'ih_'. - Make swi_net() a MI function since there is now no point in it being MD. Submitted by: cp
