traditional shortcut of defining on-disk layouts using structures of
character arrays. Unfortunately, as recently discussed on cvs-all@,
this usage is not actually sanctioned by the standards and
specifically fails on GCC/arm (unless your data structures happen to
be "naturally aligned").
The new code defines offsets/sizes for data fields and accesses
them using explicit pointer arithmetic, instead of casting to
a structure and accessing structure fields. In particular,
the new code is now clean with WARNS=6 on arm.

Remove the cdevsw() function which is now unused.
(the log is wrong, it was really devsw that was removed).
# we really need to actually document the functions in sys/conf.h as well
# as things like d_open...
to add a reference to it; otherwise, we could later access
a freed memory. This is believed to fix panics some users
were observing when running route6d(8), and is similar to
the fix in sys/netinet/if_ether.c,v 1.139 by glebius@.

1. When downloading metadata files, make sure we only download each
file once; without this fix, "freebsd-update fetch" will fail the first
time it is run if there have been no updates yet for the installed
release.
2. If the FOO kernel is installed in /boot/kernel instead of /boot/FOO
and the /boot/FOO directory does not exist, don't try to update
/boot/FOO. This is an issue only where an update involves adding a new
kernel module.
3. When removing files and directories, operate in reverse
lexographical order, in order to ensure that files are removed before
the directory which contains them.

since the calling code appears to properly handle failed allocations.

forward cases by converting from unconditional acquisition of Giant
around vnode operations to conditional acquisition:
- Remove nfsrv_access_withgiant(), and cause nfsrv_access() to now
assert that Giant will be held if it is required for the vnode.
- Add nfsrv_fhtovp_locked(), which will drop the NFS server lock if
required, and modify nfsrv_fhtovp() to conditionally acquire
Giant if required.
- In the VOP's not dealing with more than one vnode at a time (i.e.,
not involving a lookup), conditionally acquire Giant.
This removes Giant use for MPSAFE file systems for a number of quite
important RPCs, including getattr, read, write. It leaves
unconditional Giant acquisitions in vnode operations that interact
with the name space or more than one vnode at a time as these
require further work.

and correct the use of unary minus with an unsigned value. (The unary
minus here is actually being used as a bitwise operation, which is
unusual enough to deserve a clarifying cast.)
Define the xxx_OBJPATHS earlier and then use it in the xxx_make
target because each obj is actually made through that.
This allows the crunch to work with -j32 on sun4v.
The makefile generated is still poor, though. It really shouldn't use
the general 'make all' to do the submakes in the app directories being
crunched because each of those objects is listed as a dependency in
the generated crunch makefile. Doing that really requires a unique rule
to generate them.
wildcard specifications. Earlier the only wildcard syntax
was "-j 0" for "any jail". There were at least
two shortcomings in it: First, jail ID 0 was abused; it
meant "no jail" in other utils, e.g., ps(1). Second, it
was impossible to match processed not in jail, which could
be useful to rc.d developers. Therefore a new syntax is
introduced: "-j any" means any jail while "-j none" means
out of jail. The old syntax is preserved for compatibility,
but now it's deprecated because it's limited and confusing.
Update the respective regression tests. While I'm here,
make the tests more complex but sensitive: Start several
processes, some in jail and some out of jail, so we can
detect that only the right processes are killed by pkill
or matched by pgrep.
