Open Firmware-centric:
- Keep the static list of regions in platform.c instead of ofw_machdep.c
- Move various merging and sorting operations to platform.c as well
- Move apple_hacks code out of ofw_machdep.c and into platform_powermac.c,
where it belongs
- Move CHRP-specific dynamic-reconfiguration memory parsing into
platform_chrp.c instead of pretending it is shared code
in /chosen, be ihandles. The ePAPR spec makes those cross-reference phandles,
since FDT has no concept of ihandles. Have the OF FDT CI module interpret
queries about ihandles as cross-reference phandles.

by casperd(8) and its services. There is no documentation and pjdlog.h
header file is not installed in /usr/include/ to keep it private.
Unfortunately we don't have /lib/private/ at this point, only
/usr/lib/private/, so the library is installed in /lib/.

We had previously tried to flush all MKDIR_PARENT dependencies (and
all the NEWBLOCK pagedeps) by calling ffs_update(). However this will
only resolve these dependencies in direct blocks. So very large
directories with MKDIR_PARENT dependencies in indirect blocks had
not yet gotten flushed. As the directory is in the midst of doing a
complete sync, we simply defer the checking of the MKDIR_PARENT
dependencies until the indirect blocks have been sync'ed.

for extending and reusing it.
The sendfile_sync wrapper is mostly just a "mbuf transaction" wrapper,
used to indicate that the backing store for a group of mbufs has completed.
It's only being used by sendfile for now and it's only implementing a
sleep/wakeup rendezvous. However, there are other potential signaling
paths (kqueue) and other potential uses (socket zero-copy write) where the
same mechanism would also be useful.
So, with that in mind:
* extract the sendfile_sync code out into sf_sync_*() methods
* teach the sf_sync_alloc method about the current config flag -
it will eventually know about kqueue.
* move the sendfile_sync code out of do_sendfile() - the only thing
it now knows about is the sfs pointer. The guts of the sync
rendezvous (setup, rendezvous/wait, free) is now done in the
syscall wrapper.
* .. and teach the 32-bit compat sendfile call the same.
This should be a no-op. It's primarily preparation work for teaching
the sendfile_sync about kqueue notification.

shifts into the sign bit. Instead use (1U << 31) which gets the
expected result.
This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.
A similar change was made in OpenBSD.

I introduced a bug which initialized global locks
whenever the SCTP stack initialized. This was fixed in
http://svnweb.freebsd.org/changeset/base/258574
by rodrigc@. He just initialized the locks for
the default vnet. This fix reverts to the old
behaviour before r258221, which explicitly makes
sure it is only called once, because this works also on
other platforms.

If this isn't done, then a scan request whilst a scan occurs in an active

The higher level VM should not do that either.
