454af1c0e8 Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

92ae85d18e Changes to MEMORY_RBFLAGS option:
- renamed to MEMORY_DISK_RBFLAGS to better fit the rest of the
MEMORY_DISK options(4)
- change default value to RB_AUTOBOOT instead of RB_SINGLE, and adapt
the config(5) files accordingly
- document this option inside options(4)

719a906ef5 As discussed on tech-kern: mutex_init is too heavyweight for early bootstrap
phases, so move the initialization of the ksyms mutex back into main via
a function called ksyms_init. Rename the existing (but quite different)
ksyms_init* variations into ksyms_addsyms_elf() and ksyms_addsyms_explicit()
and adapt machdep code accordingly.

94d985722a It is not appropriate to call pmf_system_shutdown(9) from
doshutdownhooks(9): shutdown hooks registered by shutdownhook_establish(9)
expect to be called with interrupts disabled, but shutdown hooks
registered with pmf_device_register1(9) expect to be called with
interrupts enabled.  So I have made two changes:

1 Do not call pmf_system_shutdown() from doshutdownhooks().  Instead,
change every call to doshutdownhooks() to a call to doshutdownhooks()
followed by a call to pmf_system_shutdown().  No functional change
is intended by this change.

2 Make i386 re-enable interrupts briefly while it calls
pmf_system_shutdown().  I leave it to others either to fix the
other ports, or to factor out some MI shutdown code, as joerg@
suggests, and fix that.  Note that a functional change *is* intended
by this change.

I hope that this patch will stop us from flip-flopping between
calling doshutdownhooks() and pmf_system_shutdown() sometimes with
and sometimes without interrupts enabled.

bb33f35f20 Since files.wscons et al. are included by ~all ports anyway, include
them in the mi "files" file, and remove include statements from md files.
These shouldn't pull in additional kernel code when not in use, so it
shouldn't do any harm except a risk of namespace collisions which
should be easy to fix.

d974db0ada Merge the ppcoea-renovation branch to HEAD.
This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree.  Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

66fefd117b It's not a good idea for device drivers to modify b_flags, as they don't
need to understand the locking around that field. Instead of setting
B_ERROR, set b_error instead. b_error is 'owned' by whoever completes
the I/O request.

1ee8f4a418 Extract common code from i386, xen, and sparc64, creating
config_handle_wedges() and read_disk_sectors().  On x86, handle_wedges()
is a thin wrapper for config_handle_wedges().  Share opendisk()
across architectures.

Add kernel code in support of specifying a root partition by wedge
name.  E.g., root specifications "wedge:wd0a", "wedge:David's Root
Volume" are possible.  (Patches for config(1) coming soon.)

In support of moving disks between architectures (esp. i386 <->
evbmips), I've written a routine convertdisklabel() that ensures
that the raw partition is at RAW_DISK by following these steps:

        0 If we have read a disklabel that has a RAW_PART with
          p_offset == 0 and p_size != 0, then use that raw partition.

        1 If we have read a disklabel that has both partitions 'c'
          and 'd', and RAW_PART has p_offset != 0 or p_size == 0,
          but the other partition is suitable for a raw partition
          (p_offset == 0, p_size != 0), then swap the two partitions
          and use the new raw partition.

        2 If the architecture's raw partition is 'd', and if there
          is no partition 'd', but there is a partition 'c' that
          is suitable for a raw partition, then copy partition 'c'
          to partition 'd'.

        3 Determine the drive's last sector, using either the
          d_secperunit the drive reported, or by guessing (0x1fffffff).
          If we cannot read the drive's last sector, then fail.

        4 If we have read a disklabel that has no partition slot
          RAW_PART, then create a partition RAW_PART.  Make it span
          the whole drive.

        5 If there are fewer than MAXPARTITIONS partitions,
          then "slide" the unsuitable raw partition RAW_PART, and
          subsequent partitions, into partition slots RAW_PART+1
          and subsequent slots.  Create a raw partition at RAW_PART.
          Make it span the whole drive.

The convertdisklabel() procedure can probably stand to be simplified,
but it ought to deal with all but an extraordinarily broken disklabel,
now.

i386: compiled and tested, sparc64: compiled, evbmips: compiled.

82cc8fc351 In sys/kern/Make.tags.inc, create an intermediate variable FINDCOMM.
FINDCOMM contains the find(1) command that produces the list of
NetBSD sources that all architectures share, COMM.  For backwards
compatibility, evaluate FINDCOMM to produce ${COMM}.

In arch/evbmips/Makefile, use FINDCOMM directly, because the
command-line 'echo $COMM ...' was too long.

4d1beb764e Make ADM5120 boards use the "common" disk subroutines, such as
readdisklabel(9), which are better than the evbmips disk subroutines
at finding a BSD disklabel at a different location than the evbmips
default of sector 0, offset 64.  Helps me boot a RouterBOARD 153
from a CompactFlash containing both a Master Boot Record at sector
0, and a BSD disklabel at sector 1, offset 0.
