Otherwise make can search the path relative to certain standard paths
such as /usr/include (e.g., the line '-include $(XEN_ROOT)/.config' in
Config.mk suffers from this).

Linker command lines are order-sensitive.
Move linker options -Lfoo -lfoo from LDFLAGS to LDLIBS and place this new
variable after the objects to link. This resolves build errors in xenpagin
and blktap with recent toolchains.
rename SHLIB_CFLAGS to SHLIB_LDFLAGS
rename LDFLAGS_* to LDLIBS_*
move LDFLAGS usage after CFLAGS in CC calls
remove stale comments in xenpaging Makefile

This tool reads the CPU save records, overwrites RIP with a bogus
value, and then restores them. This is, of course, not guaranteed
to crash the guest (since the CPUs may not be executing in kernel
at the time) but it's good for breaking into some tight loops that
would be hard to debug otherwise.

xen-hptool cannot be built on ia64, because xen-hptool depends on
xc_offline_page.c and xc_offline_page.c does not support ia64.

pygrub currently has a hardcoded path of /usr/bin/python which is not
correct if the version of python at install time is not the same as
that at build time. This patch uses the existing install-wrap and
python/get-path machinery.
(It does not address the currently-existing bug that the get-path
machinery works by assuming that `python' is a symlink, rather than
querying the python interpreter for its version.)

Tmem, when called from a tmem-capable (paravirtualized) guest, makes
use of otherwise unutilized ("fallow") memory to create and manage
pools of pages that can be accessed from the guest either as
"ephemeral" pages or as "persistent" pages. In either case, the pages
are not directly addressible by the guest, only copied to and fro via
the tmem interface. Ephemeral pages are a nice place for a guest to
put recently evicted clean pages that it might need again; these pages
can be reclaimed synchronously by Xen for other guests or other uses.
Persistent pages are a nice place for a guest to put "swap" pages to
avoid sending them to disk. These pages retain data as long as the
guest lives, but count against the guest memory allocation.
Tmem pages may optionally be compressed and, in certain cases, can be
shared between guests. Tmem also handles concurrency nicely and
provides limited QoS settings to combat malicious DoS attempts.
Save/restore and live migration support is not yet provided.
Tmem is primarily targeted for an x86 64-bit hypervisor. On a 32-bit
x86 hypervisor, it has limited functionality and testing due to
limitations of the xen heap. Nearly all of tmem is
architecture-independent; three routines remain to be ported to ia64
and it should work on that architecture too. It is also structured to
be portable to non-Xen environments.
Tmem defaults off (for now) and must be enabled with a "tmem" xen boot
option (and does nothing unless a tmem-capable guest is running). The
"tmem_compress" boot option enables compression which takes about 10x
more CPU but approximately doubles the number of pages that can be
stored.
Tmem can be controlled via several "xm" commands and many interesting
tmem statistics can be obtained. A README and internal specification
will follow, but lots of useful prose about tmem, as well as Linux
patches, can be found at http://oss.oracle.com/projects/tmem .

If you use -MMD -MF then the correct .o filename is written to the
.*.d file as the compiler driver arranges everything. This was done
in 19010:275abe1c5d24 for the hypervisor.
In this patch we do the same elsewhere in the xen-unstable tree,
particularly tools/. Specifically:
* Change tools/Rules.mk to add -MMD -MF ... to CFLAGS and set DEPS.
* Remove -Wp,-MD... from every other Makefile
* Remove setting of DEPS from every other Makefile
* Ensure that every Makefile says -include $(DEPS)
* Ensure that every Makefile's clean target removes $(DEPS)
Some Makefiles were already halfway there, but often for a different
variable name eg PROG_DEP. The variable name is now standardised in
Rules.mk as DEPS.
I have done a test build with this change, on Debian etch.

The Xen tools contain a number of Python extensions written in C. The
C API to Python, used by these extensions, is not stable from one
version of Python to the next.
Our build system uses whatever version of Python is the default on the
build system at that time to build these extensions. However, the
actual scripts such as `xm' use #!/usr/bin/env python which uses
whichever version of Python is the default on the deployment system at
the time of invocation.
If for any reason these two versions of Python are not the same (eg,
because the system is built on one computer and executed on another,
or because the system's gains a more recent Python installation
alongside the original which changes the previous default), warnings
and failures occur.
In this patch I arrange for Python scripts to be installed via a
special wrapper around `install', which determines the build-time
Python version and path and then writes that into the #! line at the
point of `make install' (or `make dist'). (It can also be overridden
by setting PYTHON_PATH.)

lomount is a tool which reads and parses a partition table in a disk
image block device and then uses mount -o ...offset=... to mount it.
This is not an ideal approach. For example, if the intended
filesystem has corrupted metadata the kernel's filesystem driver may
start to write outside of the intended region. This might even be
exploitable in some perverse circumstances.
Nowadays people wanting to do this should use kpartx, which uses
devmapper to create appropriate range mappings. So lomount should be
disabled.
miniterm may well be useful but it is a clone-and-hack of an upstream
project and is currently built but not installed by default, partly
because it doesn't make sense to install on the dom0 which it might be
trying to debug.
It is probably useful to retain these two programs in the source tree
but IMO they should no longer be built by default.
The attached patch does these things:
* CONFIG_LOMOUNT and CONFIG_MINITERM in Config.mk
can enable and disable these programs
* They are disabled by default
* If CONFIG_MINITERM=y it is still built but not installed.
make -C tools/misc/miniterm install will install it.

Added the mbootpack tool, which packages multiboot boot files and
disguises them as a linux bzImage. Useful for booting Xen using
pxelinux, or another linux-only bootloader.
