Vendor revision 3648 (merge of 3647):
Additional fix to issue 168 because the change of r3642 was not sufficient.
- Make sure "CL" entry appear after its "RE" entry which the "CL" entry
should be connected with.
- Give consideration to the case that the top level "RE" entry has
already been exposed outside before its tree.

Upstream revision 3645 (merge of 3642):
Change the mechanism handling a rr_moved directory,
which is Rockridge extension that can exceed the limitation of
a maximum directory depth of ISO 9660.
- Stop reading all entries at a time.
- Connect "CL" entry to "RE" entry dynamically, which "CL" and "RE"
have information to rebuild a full directory tree.
- Tweak some related tests since we use Headsort for re-ordering
entries and it cannot make a steady order when the keies of
the entries are the same.

A "process descriptor" file descriptor is used to manage processes
without using the PID namespace. This is required for Capsicum's
Capability Mode, where the PID namespace is unavailable.
New system calls pdfork(2) and pdkill(2) offer the functional equivalents
of fork(2) and kill(2). pdgetpid(2) allows querying the PID of the remote
process for debugging purposes. The currently-unimplemented pdwait(2) will,
in the future, allow querying rusage/exit status. In the interim, poll(2)
may be used to check (and wait for) process termination.
When a process is referenced by a process descriptor, it does not issue
SIGCHLD to the parent, making it suitable for use in libraries---a common
scenario when using library compartmentalisation from within large
applications (such as web browsers). Some observers may note a similarity
to Mach task ports; process descriptors provide a subset of this behaviour,
but in a UNIX style.
This feature is enabled by "options PROCDESC", but as with several other
Capsicum kernel features, is not enabled by default in GENERIC 9.0.

Partial merge of 2431 from trunk: Retry writes on EINTR.
This should fix the SIGINT handler in bsdtar.

in order to account for LP64 targets when cross-debugging on ILP32,
allowing r224683 to compile on ILP32.
Note that thr_p{read,write}_{long,ptr}() still incorrectly use the size
of the respective types on the host rather than that on the target when
accessing the target address space which still needs to be fixed. This
means that r224683 alone may not be sufficient to solve the problem it's
intended to fix when cross-debugging.

violated ECMA-119 (ISO9660): allow reserved4 to be 0x20 in PVD.
This allows tar to read FreeBSD distribution ISO images created

In addition, merge following important bugfixes from
libarchive's release/2.8 branch:
Revision 2812:
Merge 2811 from trunk: Don't try to verify that compression-level=0
produces larger results than the default compression, since this isn't
true for all versions of liblzma.
Revision 2817:
Merge 2814 from trunk: Fix Issue 121 (mtree parser error)
http://code.google.com/p/libarchive/issues/detail?id=121
Revision 2820:
Fix issue 119.
Change the file location check that a file location does not exceed
volume block. New one is that a file content does not exceed volume
block(end of an ISO image). It is better than previous check even
if the issue did not happen.
While reading an ISO image generated by an older version of mkisofs
utility, a file location indicates the end the ISO image if its file
size is zero and it is the last file of all files of the ISO image,
so it is possible that the location value is the same as the number
of the total block of the ISO image.

Revision 2955:
Issue 134: Fix libarchive 2.8 crashing in archive_write_finish() when
the open has failed and we're trying to write Zip format.
http://code.google.com/p/libarchive/issues/detail?id=134
Revision 2958:
Followup on Issue 134:
1) Port test_open_failure to libarchive 2.8 branch to test
the problem reported in Issue 134.
This test also shows that archive_read_open() sometimes
fails to report open errors correctly.
2) Fix the bug in archive_read.c
3) Comment out the tests that close functions are invoked
promptly when open fails; that's fully fixed in libarchive 3.0,
but I don't think it's worth fixing here.

address is recorded as the ELF entry point.
o translate region 4 virtual addresses to physical addresses using
the PBVM page table.
In _kvm_kvatop() make the distinction between physical address and
core file offset a little clearer to avoid confusion. To further
enhance readability, always store the translated address into pa
so that it's obvious how the translation from va to pa happened.

fixed in the mean time, and we imported a clang snapshot soon
afterwards, so the temporary workaround of disabling clang's integrated
assembler is no longer needed.
In this particular case, using e.g. DEBUG_FLAGS=-g causes clang to
output certain directives into assembly that our version of GNU as
chokes on.

This includes a structural change regarding atomic ops. Previously they
were enabled on all platforms unless we had knowledge that they did not
work. However both work performed by marius@ on sparc64 and the fact that
the 9.8.x branch is fussier in this area has demonstrated that this is
not a safe approach. So I've modified a patch provided by marius to
enable them for i386, amd64, and ia64 only.

In C90, NULL is guaranteed to be declared in <stddef.h> and also in
<string.h>. Though the correct way to define NULL in FreeBSD is to
include <sys/_null.h>, other parts of libstand still require <string.h>
