0fa2250548 Build the powerpc64 kernel as a position-independent executable. At startup,
it processes its own ELF relocations and can be loaded and run in place at
any physical/virtual address.

NB: This requires an updated loader to boot!

only release, no new features have been added.

Please note that this version requires C++11 support to build; see
UPDATING for more information.

968d62e1a1 Use a set of ELF Tool Chain tools by default
These tools are now from the ELF Tool Chain project:

 * addr2line
 * elfcopy (strip)
 * nm
 * size
 * strings

The binutils versions are available by setting in src.conf:
WITHOUT_ELFTOOLCHAIN_TOOLS=yes

Thanks to antoine@ for multiple exp-runs and diagnosing many of the
failures.

603eaf792b Renove faith(4) and faithd(8) from base. It looks like industry
have chosen different (and more traditional) stateless/statuful
NAT64 as translation mechanism. Last non-trivial commits to both
faith(4) and faithd(8) happened more than 12 years ago, so I assume
it is time to drop RFC3142 in FreeBSD.

2d6f6d6373 Enable vt(4) by default
vt(4) is a new console driver which brings features such as:
    o  Support for Unicode and double-width characters
    o  Integration with the KMS kernel video drivers
    o  Support for UEFI

You may need to update your console settings in /etc/rc.conf, most
probably the keymap. During boot, /etc/rc.d/syscons will indicate what
you need to do.

vt(4) still has issues and lacks some features compared to syscons(4).
See the wiki for up-to-date information:
    https://wiki.freebsd.org/Newcons

If you want to keep using syscons(4), you can do so by adding the
following line to /boot/loader.conf:
    kern.vty=sc

232490c660 Make mmap() of the console device when using ofwfb work like other supported
framebuffer drivers. This lets ofwfb work with xf86-video-scfb and makes
the driver much more generic and less PCI-centric. This changes some

1cb207df04 Change suggestion how to set MAKESYSPATH as broken incremental build
workaround. Magic ".../share/mk" (search directories up to /)
does not work for f.e. /usr/src/gnu/lib/libgcc because the path
inside is starting from /usr/obj hierarchy and ends up in
/usr/share/mk, not in the /usr/src/share/mk where src.opts.mk is.
IMHO proper fixing of incremental build is needed urgently.

8c7ec47a40 Move atf-sh from /usr/bin/ to /usr/libexec/
In r266650, we made libatf-c and libatf-c++ private libraries so that no
components outside of the source tree could unintendedly depend on them.

This change does the same for the "atf-sh library" by moving the atf-sh
interpreter from its public location in /usr/bin/ to the private location
in /usr/libexec/.  Our build system will ensure that our own test programs
use the right binary, but users won't be able to depend on atf-sh by
"mistake".

Committing this now to ride the UPDATING notice added with r267172 today.

727a7ce81b Homogenize libatf-* version numbers with upstream.
The libatf-* major version numbers in FreeBSD were one version ahead of
upstream because, when atf was first imported into FreeBSD, the upstream
numbers were not respected.  This is just confusing and bound to cause
problems down the road.

Fix this by taking advantage of the fact that libatf-* are now private
and that atf is not yet built by default.  However, and unfortunately, a
clean build is needed for tests to continue working once "make
delete-old-libs" has been run; hence the note in UPDATING.

bd871f14b7 bsd.compiler.mk was implicitly included by bsd.own.mk in historical
versions. With its movement to src.opts.mk, bsd.prog.mk was testing
COMPILER_TYPE without including the bsd.compiler.mk anymore. In the
source tree, this caused no problems, for reasons that aren't clear,
but does cause problems outside of the source tree. Allow
bsd.compiler.mk to be included multiple times safely, and always
include bsd.compiler.mk at the top of bsd.prog.mk. Resist the urge to
put it in bsd.init.mk, since that would reintroduce the implicit
include.

those to be changed. When /etc/ttys has the "3wire" type (without a
baudrate) for the serial port that is the low-level console, then
this change has no effect.

3ad1a09169 Rather than require a makeoptions DEBUG to get debug correct,
add it in kern.mk, but only if we're using clang. While this
option is supported by both clang and gcc, in the future there
may be changes to clang which change the defaults that require
a tweak to build our kernel such that other tools in our tree
will work. Set a good example by forcing -gdwarf-2 only for
clang builds, and only if the user hasn't specified another
dwarf level already. Update UPDATING to reflect the changed
state of affairs. This also keeps us from having to update
all the ARM kernels to add this, and also keeps us from
in the future having to update all the MIPS kernels and is
one less place the user will have to know to do something
special for clang and one less thing developers will need
to do when moving an architecture to clang.

f785676f2a Upgrade our copy of llvm/clang to 3.4 release. This version supports
all of the features in the current working draft of the upcoming C++
standard, provisionally named C++1y.

The code generator's performance is greatly increased, and the loop
auto-vectorizer is now enabled at -Os and -O2 in addition to -O3.  The
PowerPC backend has made several major improvements to code generation
quality and compile time, and the X86, SPARC, ARM32, Aarch64 and SystemZ
backends have all seen major feature work.
