riastradh | t_signal_and_sp: Add sparc support.
Seems fine! Would be nice if we had a well-known macro to abstract
PIC vs non-PIC `sethi/ori/(ld)' like I invented here, to reduce
needless #ifdef __PIC__ conditionals.

isaki | Move machine dependent AUDIO_BLK_MS default value to <machine/param.h>.
If the port has __AUDIO_BLK_MS in <machine/param.h>, it will be used.
Otherwise the default value (currently 10 msec) defined in audio.c will
be used. This mechanism is for very old ports which cannot satisfactorily
handle 10 msec block. Currently hppa, m68k, sh3, sparc(!64) and vax are.
For port maintainers, if general models in your port cannot satisfactorily
handle 10 msec block, please consider to define your suitable longer period
(40 msec would be a good first choice).
But please don't be eager to make the default value shorter.
<machine/param.h> was discussed in source-changes-d. It's better than
ifdef storm, or adding 60+ new header files in every arch/*/include/
directories for this. Thanks mrg@, ad@, and everyone.

joerg | Change CMSG_SPACE and CMSG_LEN to provide Integer Constant Expressions
again. This was changed in sys/socket.h r1.51 to work around fallout
from the IPv6 aux data migration. It broke the historic ABI on some
platforms. This commit restores compatibility for netbsd32 code on such
platforms and provides a template for future changes to the CMSG_*
alignment. Revert PCC/Clang workarounds in postfix and tmux.

Remove separate mb_map. The nmbclusters is computed at boot time based
on the amount of physical memory and limited by NMBCLUSTERS if present.
Architectures without direct mapping also limit it based on the kmem_map
size, which is used as backing store. On i386 and ARM, the maximum KVA
used for mbuf clusters is limited to 64MB by default.
The old default limits and limits based on GATEWAY have been removed.
key_registered_sb_max is hard-wired to a value derived from 2048
clusters.

| 17-Jul-2002 |
thorpej | Instead of using a matrix of configured CPU types, first count
how many CPU types are configured into the kernel. Then, use this
information to define the CPU predicate macros according to the
following rules:
1. If support for a CPU type is not configured into the kernel,
then the test is always false.
2. Otherwise, if only one CPU type is configured into the kernel,
then the test is always true.
3. Otherwise, we have to reference the cputyp variable.
Use a similar strategy for short-cutting the page size related
definitions.

as (CPU_ISSUN4 || CPU_ISSUN4C) and (CPU_ISSUN4C || CPU_ISSUN4M),
respectively. The compiler can still optimize as desired by expressing
them this way, and it simplifies adding new tests.
While here, just remove CPU_ISSUN4MOR4U; it's not used by anything.

uwe | microSPARC-IIep is a sun4m but with an integrated PCI controller.
In a lot of places (like pmap &c) we want it to be treated as SUN4M.
But since various low-level things are done very differently from
normal sparcs (and since for now it requires a relocated kernel
anyway), the MSIIEP kernels are not supposed to support any other
system. So when MSIIEP is defined - insist on SUN4M defined and SUN4
and SUN4C not defined.

- for sizeof(void *) == 8 arch, this is mandatory. MHLEN is too small
already (less than 80) and there are chances for unwanted packet loss due
to m_pullup restriction.
- for other cases, the change should avoid allocating clusters in most cases
(even when you have IPv4 IPsec tunnel, or IPv6 with moderate amount of
extension header)

whatever), please backout the change for your arch.

Reduce default AUDIO_BLK_MS from 40msec to 10msec on all platform except m68k
(m68k uses 40msec default as before). And remove the option from GENERIC.
- It's not good idea to set such parameter in individual GENERICs.
- 4msec is (probably no problem for most modern real hardware but)
too aggressive to be default.
- 10msec is too severe for antique machines but it's hard to draw a line.
Set AUDIO_BLK_MS 40 msec on other old(slow) architectures not only m68k.
Thanks tsutsui@ for comment about architecture choice.
And move it from audiodef.h to audio.c as suggested by joerg@.
Move machine dependent AUDIO_BLK_MS default value to <machine/param.h>.
If the port has __AUDIO_BLK_MS in <machine/param.h>, it will be used.
Otherwise the default value (currently 10 msec) defined in audio.c will
be used. This mechanism is for very old ports which cannot satisfactorily
handle 10 msec block. Currently hppa, m68k, sh3, sparc(!64) and vax are.
For port maintainers, if general models in your port cannot satisfactorily
handle 10 msec block, please consider to define your suitable longer period
(40 msec would be a good first choice).
But please don't be eager to make the default value shorter.
<machine/param.h> was discussed in source-changes-d. It's better than
ifdef storm, or adding 60+ new header files in every arch/*/include/
directories for this. Thanks mrg@, ad@, and everyone.
