longer create a pv entry for that mapping. (The two exceptions are
mappings into the kernel's exec and pipe submaps.) Consequently, there is
no reason for get_pv_entry() to dig deep into the free page queues, i.e.,
use VM_ALLOC_SYSTEM, by default. This revision changes get_pv_entry() to
use VM_ALLOC_NORMAL by default, i.e., before calling pmap_collect() to
reclaim pv entries.

ENOENT if the option wasn't provided, instead of setting it to 0.
xfs however didn't catch up on this, so it assumed something went bad if
vfs_getopts() sets the error to non-zero, and just returns the error.
Unbreak xfs mount by just ignoring the error if vfs_getopts() sets the
error to ENOENT, as we should have sane defaults.

GNU tar 1.17's implementation of --posix --sparse,
at the cost of losing compatibility with GNU tar 1.16.
Fortunately, the 1.17 implementation actually makes sense,
so the libarchive code is now a bit more straightforward
than before.
Background: GNU tar 1.16 defined a new way to store
sparse files in --posix archives. Unfortunately,
the implementation incorrectly inserted several
blocks of null padding after each such entry.
As a result, non-GNU tar implementations saw the
archive as truncated after any sparse entry.
This was fixed in GNU tar 1.17 at the cost of
losing compatibility with GNU tar 1.16 for this
new format (which is not the default, so hopefully
rarely used). Libarchive recently gained support
for reading the GNU tar 1.16 formats; this commit
updates it to read the GNU tar 1.17 variant instead.

in most cases, except one. The 'restart' case was not working as expected. Specifically,
it would stop both lockd and statd, but it would restart only statd (which appears first
in the script). This is because rc.subr(8) contains code to guard against infinite
recursion in the 'restart' casae.
To fix this use the traditional approach of controlling only one server from one script by
breaking out rc.d/nfslocking into its contituent parts: rc.d/lockd and rc.d/statd. Keep
rc.d/nfslocking around but don't include it in the boot rcorder(8)ing.
