tsutsui | 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@:
https://mail-index.netbsd.org/source-changes-d/2020/01/thread1.html#012035
https://mail-index.netbsd.org/tech-kern/2020/01/thread1.html#025954
Should be pulled up to netbsd-9.

tsutsui | Make common kernel module binaries work on both sun3 and sun3x.
Tested on 3/160 (on TME) and (real) 3/80.
XXX: module files can be loaded only on single user?

pooka | Raise the blade, make the change, don't quite rearrange to where
it's sane. But improves the non-monolithic kernel case anyway.

so move it into sys/param.h.

move parts that are the same from vmparam3{,x}.h to vmparam.h.
|
| 1.29 |
| 01-May-2001 |
thorpej | Per discussion w/ chuck and chuck, restructure the md page stuff
to use a structure called "vm_page_md", and use __HAVE_VM_PAGE_MD
and __HAVE_PMAP_PHYSSEG.
|
| 1.28 |
| 29-Apr-2001 |
thorpej | Add a VM_MDPAGE_MEMBERS macro that defines pmap-specific data for
each vm_page structure. Add a VM_MDPAGE_INIT() macro to init this
data when pages are initialized by UVM. These macros are mandatory,
but ports may #define them to nothing if they are not needed/used.
This deprecates struct pmap_physseg. As a transitional measure,
allow a port to #define PMAP_PHYSSEG so that it can continue to
use it until its pmap is converted to use VM_MDPAGE_MEMBERS.
Use all this stuff to eliminate a lot of extra work in the Alpha
pmap module (it's smaller and faster now). Changes to other pmap
modules will follow.

A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.
