tsutsui | Bump DFLSSIZ from 512KB to 2MB on all hp300 pmap m68k ports.
Some modern applications could require 512KB buffer on stack and
no particular comment on port-m68k@:

Add MAX/MIN PAGE_SIZE and PAGE_SHIFT definitions of m68k for jemalloc(3).
Background:
- All m68k ports have fixed PAGE_SIZE value in their kernels,
but each port uses different PAGE_SIZE value (4096 or 8192)
due to historical reasons.
- Currently module(7) binaries are built per each port so
all m68k kernel sources don't support run-time variable PAGE_SIZE.
- MI <uvm/uvm_param.h> assumes that the port supports a variable
PAGE_SIZE on module(7) builds if both MAX_PAGE_SIZE and MIN_PAGE_SIZE
are defined and they have different values.
- On the other hand, jemalloc(3) checks MAX_PAGE_SHIFT in
src/external/bsd/jemalloc/include/jemalloc/internal/jemalloc_internal_defs.h
for internal optimization.
- m68k ports share userland binaries (especially pkgsrc binaries)
among all ports, so we need to define MAX_PAGE_SHIFT as 13 to
support m68k ports where PAGE_SIZE==8192.
(though this would affect only if static binaries built on
4k page hosts are executed on 8k page hosts)
To solve these inconsistency on PAGE_SIZE definitions,
we should have an independent PAGE_SIZE related definitions
for userland, but it requires major reorganization.
For now (especially for netbsd-9) we define MAX/MIN PAGE_SIZE and
PAGE_SHIFT values in <m68k/vmparam.h> only in !defined(_KERNEL) case.
Discussed on source-changes-d@ and tech-kern@ with christos@ and thorpej@:

Should be pulled up to netbsd-9.

XXX: we also need MAX_PAGE_SIZE in somewhere for newer jemalloc?

thorpej | Minor tweak to the pv_table management in the Hibler-derived m68k pmaps:
The head of the list is now a pv_header, which contains the first pv_entry
as well as a 16-bit attributes field (replaces the pmap_attributes array
plus the pv_entry::pv_flags field) as a 16-bit count of caller-specified
cache-inhibited mappings.
Tested on hp300 (shared pmap_motorola.c), changes to atari and amiga copies
are purely mechanical.

drochner | Initial import of the known working kernel bits for the NetBSD/cesfic
port. cesfic is a VME board with one or two mc68040 processors. See
the README file for details.
The port is working well with a.out userland, there are some problems
with ELF still, like applications running out of memory where it is not
expected. Some parts, in particular the pmap (which was taken from hp300
four years ago), need updating, but this is easier done within the NetBSD
CVS tree.
