.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.

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.

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.

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().
