UPA is just a physical incarnation of our mainbus0.
Evidence:
- There can only be one!
- The firmware node coresponding to it is the root of the OF tree
So: remove the unused (and uncompilable) upa.c, remove upavar.h after
moving the only declaration used from it to autoconf.h.
kernel using the $TOOLDIR toolchain. If kern doesn't contain `/', it will
be searched for in ${KERNCONFDIR} (typically, sys/arch/${MACHINE}/conf).
- Improve ./build.sh usage.
- Add some examples to the documentation.
This is heavily based on [toolchain/18739] from Alan Barrett <apb@cequrux.com>,
with improvements by me.
- If the BIOS reports the same memory cluster multiple times,
only allocate the extent once.
- If we fail to allocate an extent,
don't add it to mem_clusters and don't increment mem_cluster_cnt.
- When loading the physical extents,
make sure we don't try to add an extent with zero length (seg_start == tmp).

As discussed (briefly) on tech-userlevel, fix our quad support to work
correctly on LP64 platforms. This is mostly just s/long/int/ in the
appropriate places.
clean up some other stuff along the way, including:
- use m68k/cacheops.*, remove duplicates from cpu.h.
- centralize a few declarations in (all the copies of) cpu.h.
- define M68K_VAC on platforms which have a VAC.
- switch the sun platforms to the (now common) proc_trampoline().
- do the phys_map thang on the sun platforms too, no reason not to.
children nodes have reached their final state before augmenting the
parent. This fixes an obscure inconsistency of the space in the
vm_map tree that gcc 3.2 triggers when compiling isp.o on alpha. (this
only led to some leaked space). from art@openbsd.org
alignment code. (There was nothing wrong with the original code path
other than it was slightly slower if the buffer was already aligned).
Also, catch another corner case related to alignment/length of the
last 1-7 bytes.
