binutils 2.22 changed ld default from --copy-dt-needed-entries
to -no-copy-dt-needed-entries. This revealed that some objects
are linked implicitly with libtinfo and newer ld fails to build
relevant executables.
Below is short explanation why we should not do that...
http://fedoraproject.org/wiki/UnderstandingDSOLinkChange says:
The default behaviour for ld (my note: before version 2.22) allows
users to 'indirectly' link to required objects/libraries through
intermediate objects/libraries. While this is convenient, it can
also be dangerous because it makes your program's dependencies tied
to the dependencies of other objects. If those objects ever change
their linkages, they can break your program without any changes
to your own code!

An increasing version and/or release number helps to update existing
packages without --force as in "rpm Uvh --force xen.rpm". Instead its
possible to do "rpm -Fvh *.rpm" to update only already installed
packages.
The usage of --force disables essentials checks such as file conflict
detection. As a result the new xen.rpm may overwrite files owned by
other packages.
With the current way of calculating version-release it is difficult to
get an increasing release number into the spec file. The release is
always zero unless "make make XEN_VENDORVERSION=`date +.%s`" is used,
which has the bad side effect that xen.gz always gets a different
filename every time.
Update mkrpm to recognize PKG_RELEASE=. Its value will be appended to
the Release string. It can be filled with a time stamp, like:
make rpmball PKG_RELEASE="`date +%Y%m%d%H%M%S`"

A number of changes to XEN_SYSCTL_topologyinfo interface:
* Instead of copying data for each field in xen_sysctl_topologyinfo separately
put cpu/socket/node into a single structure and do a single copy for each
processor.
* A NULL cputopo handle passed is a request for maximum number of CPUs
(num_cpus). If cputopo is valid and num_cpus is smaller than the number of
CPUs in the system then -ENOBUFS is returned (and correct num_cpus is provided)
* Do not use max_cpu_index, which is almost always used for calculating number
CPUs (thus requiring adding or subtracting one), replace it with num_cpus.
* There is no need to copy whole op in sysctl to user at the end, we only need
num_cpus.
* Rename xen_sysctl_topologyinfo and XEN_SYSCTL_topologyinfo to reflect the fact
that these are used for CPU topology. Subsequent patch will add support for
PCI topology sysctl.
* Replace INVALID_TOPOLOGY_ID with "XEN_"-prefixed macros for each invalid type
(core, socket, node).

Changes in v3:
1. Put mini-os targets in main Makefile.
2. Stubdom clean and distclean don't depend on mini-os-dir.
Changes in v2:
1. Use hash in Config.mk.
Coverity uses several heuristics to identify when one case statement
legitimately falls through into the next, and a comment as the final item in a
case statement is one heuristic (the assumption being that it is a
justification for the fallthrough).
Use this to perform an audit of defects and hide the legitimate fallthroughs.
There are two bugfixes identified in the audit, both minor:
* 'n' command line handling for gtracestat
* BKSPC handling in xentop
All other identified defaults are legitimate fallthoughs

The original rule to target "distclean" in tools/Rules.mk was in effect
"make clean". It should be "make distclean".
However not all Makefiles in subdirectories have distclean target
defined. So this patch also adds a bunch of distclean targets to various
Makefiles. They only depend on clean target and don't have any actions
in most cases.
With the patch applied, following command outputs 0 results:
find tools -name 'Makefile*' -exec grep -L 'distclean' {} \+ \

Ocaml and libfsimage are known to have distclean defined in a dedicated

The existing makefile was awkward with needing to express conditional
inclusion for both the build and install rules, and contained both split and
unsplit long lines.
The INSTALL_* rules now contain the conditional inclusion information, while
the TARGET_* rules generate the build list from the complete install list,
less the minority of scripts which simply need copying into place. Comments
are introduces to aid clarity.
In addition, collect the CFLAGS expressions, remove the unreferenced and empty
HDRS list, and restrict the libxc internals build fix to the offending
binaries.
No functional change as a result of this patch, but it is rather more simple
to add or remove utilities.

The current usage of LIBEXEC is bogus. It describes the directory for
private xen executables. Other places create their own, similar
libexecdir path as $prefix/lib/xen/*.
Additional two other variables are used to describe similar paths:
PRIVATE_BINDIR and PRIVATE_PREFIX
The autoconf documentation refers to libexec as a directory for
executables and stuff which is called by other programs, not by the
user.
Adjust all places that want libexecdir as a target path. LIBEXEC refers
now to the base directory. Three convenience variables are used to refer
to paths to private binaries, libs and include files.
In the systemd files LIBEXEC_BIN is substituted, so this variable has to
be present in autoconf. All other variables are expanded in Paths.mk
because they are only used in Makefiles.
Most users of LIBEXEC are updated to use LIBEXEC_BIN because that is
what they want.
Users of PRIVATE_BINDIR are updated to use LIBEXEC_BIN because that is
what they want. PRIVATE_BINDIR and PRIVATE_PREFIX usage is removed by
this patch, in favour of LIBXEC_BIN and LIBEXEC
An internal libxl function was removed. A single helper to retrieve
LIBEXEC_BIN remains.
As suggested by the autoconf documentation, configure appends the
package name to LIBEXEC to make sure the provided directory really
refers to xen. This makes sure "make uninstall" preserves the real
libexecdir.

At the moment, making a release tarball is an annoyingly manual
process that involves running "git archive" into a temporary directory.
Script this process up and make a target, so that the release manager
can simply type "make src-tarball-release" and have everything show up
nice and neat in dist/xen-$version.tar.gz. "make src-tarball" will
make a version number based on git describe, which will typically have
the most recent tag, number of commits since that tag, and the git
commit id of the current HEAD.

Even if xen is configured and compiled with different --prefix= so that
it operates entirely below $prefix, the resulting package from 'make

Use an environment name to give a different name.
This can be used like this:
suffix=-bugN
prefix=/opx/xen/staging${suffix}
./configure --prefix=${prefix}
make rpmball PKG_SUFFIX=${suffix}
The result will be "xen-bugN.rpm" instead of "xen.rpm". The benefit is that

With the number of these growing it becomes increasingly desirable to
not repeatedly alter the sysctl interface to accommodate them. Replace
the explicit listing of numbered states by arrays, unused fields of
which will remain untouched by the hypercall.
The adjusted sysctl interface at once fixes an unrelated shortcoming
of the original one: The "nr" field, specifying the size of the
"triggers" and "residencies" arrays, has to be an input (along with
being an output), which the previous implementation didn't obey to.
Note that the bouncing direction in the libxc interface at once gets
corrected to OUT (was BOTH).
