8abe0d6b1c Adjust for the new "reaper" kernel thread: do not free the vmspace and 
u-area in machine-dependent code.  Instead, call exit2() to schedule
the reaper to free them for us, once it is safe to do so (i.e. we are
no longer running on the dead proc's vmspace and stack).

5fa7eee1ff don't define __BUS_SPACE_COMPAT_OLDDEFS by default. As stated in 
bus_space(9), if drivers want it (they shouldn't; easy to convert) they

the interfaces were (slightly) changed, and no code in the source tree

eb32016a95 Split up using BWX for PCI config and bus access. Default to using BWX for 
the former, but not the latter.  Hopefully, this will address some problems
people have been experiencing w/ some devices on Pyxis systems when BWX
is used for bus access.  (If it's not used for PCI config access, we can
get fatal machine checks while probing behind PCI-PCI bridges!!)

is
6054d626f9 Switching dev/ic/lpt.c to use spllpt() instead of spltty(). It doesn't use 
tty structures, and on some machines (namely the DraCo internal lpt, and some
multi-i/o boards for Amigas and DraCos), tying spltty to the pretty high printer
interupt level would hurt serial performance.

On all affected ports but Amiga, spllpt() has been defined in machine/intr.h
to be spltty(), thus preserving old behaviour. Portmasters are encouraged to
change is, if they feel something else is better (e.g., one of its own were
possible).

the recent bug where Multias around the world have been aborting back to
SRM with no message at all as they tried to attach a TGA or VGA console,

ff376fbd03 Doh! Jason caught me being really stupid. There isn't necessarily 
a linear 0..N mapping out of alpha_cpu_whami - which is what I was
using to index the new cpu machine check array. This is a quick hack
back to just using the first element while I think of a kinder function
that will do the function (per-platform) of whami->VIRTUAL CPU ID, which
if you think about it, is really necessary anyway.

 * There can be only one TurboLaser, and we'll overload it
 * with a bitmap of found turbo laser nodes. Note that
 * these are just the actual hard TL node IDS that we
 * discover here, not the virtual IDs that get assigned
 * to CPUs. During TLSB specific error handling we
 * only need to know which actual TLSB slots have boards
 * in them (irrespective of how many CPUs they have).

adf058f0f7 There can only be one TurboLaser node, and now we'll overload 
into the integer tlsb_found a bit map of found nodes and export
it to the rest of the kernel. This is so that at machine check
time when we're doing some TLSB/KFTXX error handling we don't
have to attempt a badaddr to look at all TLSB nodes (which will
just be too sad to try...).

In this case, all it has in it are the never-referenced printable names
for the ELF sections themselves. It's located at the end of the (ramdisk)

651b44e211 Rework the way kernel include files are installed. In the new method, 
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

616125f8d1 Deal with a hardware bug in Pass 1 and Pass 2 Pyxis chips. Basically, 
the scatter/gather TLB cannot be invalidated on these chips.  So, to
work around this, we configure the otherwise unsed DMA Window 2 as a
2M SGMAP window at 128M, point all of its page table entries at the
DMA spill page, and, when the TLB is to be invalidated, put the PCI bus
into loopback mode, and create a target hit on Window 2 every 64k for
the number of TLB entries (plus a few ... it seems to not work unless
we read a few extra times), forcing out old TLB entries to make room for
the new, dummy target hits.
