8bcc0d3f95 Update nwfs_lookup() to match the current cache_lookup() API.
cache_lookup() has returned a ref'ed and locked vnode since
vfs_cache.c:1.96, dated Tue Mar 29 12:59:06 2005 UTC.  This change
is similar to the change made to smbfs_lookup() in smbfs_vnops.c:1.58.

3554cddbfa Reflect mpsafety of the underlying filesystem in the nullfs image.
I benchmarked this by simultaneously extracting 4 large tarballs (basically
world images) on a 4-processor AMD64 system, in a malloc-backed md.

With this patch, system time was reduced by 43%, and wall clock time by 33%.

d31c91fbcf Apply the same fix to a potential race in the ISDOTDOT code in
cd9660_lookup() that was used to fix an actual race in ufs_lookup.c:1.78.
This is not currently a hazard, but the bug would be activated by
marking cd9660 as MPSAFE.

822923447e Let modules use the kernel's opt_*.h files if built along with
the kernel by wrapping all targets for fake opt_*.h files in
.if defined(KERNBUILDDIR).  Thus, such fake files won't be
created at all if modules are built with the kernel.

Some modules undergo cleanup like removing unused or unneeded
options or .h files, without which they wouldn't build this way
or the other.

10d645b7e5 In preparation for making the modules actually use opt_*.h files
provided in the kernel build directory, fix modules that were
failing to build this way due to not quite correct kernel option
usage.  In particular:

ng_mppc.c uses two complementary options, both of which are listed
in sys/conf/files.  Ideally, there should be a separate option for
including ng_mppc.c in kernel build, but now only
NETGRAPH_MPPC_ENCRYPTION is usable anyway, the other one requires
proprietary files.

nwfs and smbfs were trying to ensure they were built with proper
network components, but the check was rather questionable.

12d360453c Close a race in the ufs_lookup() code that handles the ISDOTDOT
case by saving the value of dp->i_ino before unlocking the vnode
for the current directory and passing the saved value to VFS_VGET().

Without this change, another thread can overwrite dp->i_ino after
the current directory is unlocked, causing  ufs_lookup() to lock
and return the wrong vnode in place of the vnode for its parent
directory.  A deadlock can occur if dp->i_ino was changed to a
subdirectory of the current directory because the root to leaf vnode
lock ordering will be violated.  A vnode lock can be leaked if
dp->i_ino was changed to point to the current directory, which
causes the current vnode lock for the current directory to be
recursed, which confuses lookup() into calling vrele() when it
should be calling vput().

The probability of this bug being triggered seems to be quite low
unless the sysctl variable debug.vfscache is set to 0.

3c2adf40e9 Add a default value for VM_BCACHE_SIZE_MAX of 400MB. This is copied from
amd64, and is a factor of 3 less than the value previously auto-sized on
a 12GB machine, which would cause an overflow in calculations involving the
maxbcache int, causing bufinit() to loop forever at boot.

f098dcded5 Partially revert revision 1.66, which contained a change that did not
correspond to the commit log.  It changed the maxswzone and maxbcache
parameters from int to long, without changing the extern definitions
in <sys/buf.h>.

In fact it's a good thing it did not, because other parts of the system
are not yet ready for this, and on large-memory sparc machines it causes
severe filesystem damage if you try.

The worst effect of the change was that the tunables controlling the
above variables stopped working.  These were necessary to allow such
large sparc64 machines (with >12GB RAM) to boot, since sparc64 did not
set a hard-coded upper limit on these parameters and they ended
up overflowing an int, causing an infinite loop at boot in bufinit().
