it was there so that big endian and little endian devices could both be
present, however that is not the case on the macppc machines.

poll(2) functionality instead of emulating it via the select backend.
Adapted from NetBSD and including some changes from FreeBSD.

not work properly (endian?) wdc should work fine, but has not been tested

Move the ddb files form macppc/macppc to powerpc/ddb, so that mvmeppc
can benefit from the better ddb that was in macppc.

type characteristics.
internal_types.h will contain only settings invisible from standard C, e.g.,
in the __* or _[A-Z]* namespace, and be reused by files like limits.h.
This allows us to shorten machine/limits.h greatly, as all the common defines
are now in sys/limits.h, plus a small stub in internal_types.h.
Tested on all arches as far as I know.
Approved after discussion with art, millert, deraadt, and others.

the spill list for each PTEG, the V->P translations are stored in
trees for each pmap. All valid kernel mappings are preallocated
in 1-1 memory so that tlb spill/loads for kernel accesses can be
looked up while physical, user mappings are not guaranteed to
be 1-1 mapped, thus the kernel must go virtual to look up user
mappings. While this is more expensive, the tree search is much
lower cost than the long linked list search. Also on each pmap_remove()
it was necessary to search the linked lists for each possible mapping,
now it just looks up the entry in the tree.
This change gives a 25-36% speedup in 'make build' time. What was
around 2:50 is now around 1:55 on a 733MHz G4.
This change causes a likely existing bug to appear quite often,
it deals with the segment register invalidation in kernel mode.
Because of that problem, currently this change limits the physical
memory used to 256MB. This limitation will be fixed soon, it is not
an error in the pmap code.

This allows to run the X server on macppc with securelevel=1, given that
machdep.allowaperture is != 0.

The patch allows you to change the value of NMBCLUSTERS, BUFCACHEPERCENT
and NKMEMPAGES using the config command, instead of recompiling the kernel.
This is the kernel part of the patch. I have compiled it on i386, sparc64,
alpha and macppc. -moj ok art@ maja@

Add some very simple code to auto-size the kmem_map. We take the
amount of physical memory, divide it by 4, and then allow machine
dependent code to place upper and lower bounds on the size. Export
the computed value to userspace via the new "vm.nkmempages" sysctl.
NKMEMCLUSTERS is now deprecated and will generate an error if you
attempt to use it. The new option, should you choose to use it,
is called NKMEMPAGES, and two new options NKMEMPAGES_MIN and
NKMEMPAGES_MAX allow the user to configure the bounds in the kernel
config file.

instead of doing fork1, cpu_set_kpc. This lets us retire cpu_set_kpc and
avoid a multiprocessor race.
This commit breaks vax because it doesn't look like any other arch, someone
working on vax might want to look at this and try to adapt the code to be
more like the rest of the world.
Idea and uvm parts from NetBSD.
