Do not share synchronization variables between the trap handler and
the softirq handler, as this will cause problems. Abstract the
synchronization bits into functions. Make the synchronization code
aware of a panic, so that spinning with interrupts disabled is
avoided.
To avoid problems with MCEs happening while we're doing recovery
actions in the softirq handler, implement a deferred list of telemetry
structures, using the mctelem interfaces. Thist list will get updated
atomically, so any additional MCEs will not cause error telemetry to
be missed or not handled.

Previously, by default we would install our python modules into
/usr/lib/python/xen, for example /usr/lib/python/xen/__init__.py.
Upstream python's standard install location (a) includes the Python
version number and (b) puts things in site-packages by default.
Our best conjecture for the reason for this was an attempt to make the
installs portable between different python versions. However, that
doesn't work because compiled python modules (.pyc), and C python
extensions corresponding to one version of python, are not compatible
across different versions of python.
This is why upstream include the version number.
site-packages is the standard location for locally-installed packages
and is automatically included on the python search path.
In this change, we abandon our own unusual python path setup:
* Invoke setup.py in an entirely standard manner. We pass
PREFIX and DESTDIR using the appropriate options provided by
setup.py for those purposes (adding them to setup.py calls
which were previously lacking them).
* Since the installation locations are now on the standard
python path, we no longer need to add anything to the path
in any of our python utilities. Therefore remove all that
code from every python script. (Many of these scripts
unconditionally added /usr/lib/python and /usr/lib64/python which
is wrong even in the old world.)
* There is no longer any special `Xen python path'. xen-python-path
is no longer needed. It is no longer called by anything in our
tree. However since out-of-tree callers may still invoke it, we
retain it. It now prints a fixed string referring to a directory
which does not to exist; callers (who use it to augment their
python path) will thus add a nonexistent directory to their python
path which is harmless.
* Remove various workarounds including use of setup.py --home
(which is intended for something completely different).
* Remove tests for the XEN_PYTHON_NATIVE_INSTALL build-time
environment variable. The new behaviour is the behaviour which we
should have had if this variable had been set. That is, it is now
as if this variable was always set but also bugs in the resulting
install have been fixed.
This should be a proper fix for the bug addressed by c/s 19515.

When xend calls xc.test_assign_device, xend does not have to give
the domain-ID of a guest domain.
This patch gives domain-ID 0 to xc.test_assign_device.
The following methods give domain-ID 0 to xc.test_assign_device
currently.
- setupDevice@xend/server/pciif.py
- pciinfo@xend/XendNode.py

attached patch lets python install the modules into
DESTDIR/PREFIX as before, but lets python search
the modules in PREFIX rather DESTDIR/PREFIX.
This prevents failures about not finding python modules
after files have been installed into PREFIX.

While in the comments to an earlier submitted (and already applied)
patch I claimed to have fixed the need to specify both "nolapic" and
"noapic" when "nolapic" alone should already have the intended effect,
this doesn't appear to be the case. Here are the missing bits.

On RHEL5.2, ifup ${bridge} fails if ${bridge} != ${netdev},
because RHEL5.2's ifup ${bridge} runs the following sequence:
1. Search CONFIG that has the same mac address of ${bridge}.=20
ifcfg-${netdev} is found.
2. Run "ip link set dev ${netdev} up".
# ${bridge} is expected.
3. Output "Failed to bring up ${netdev}."
Because ${netdev} does not exist.
Thus, do_ifup() should not use ifup if ${bridge} != ${netdev}.

vector_channel[], as its name already says, is vector-, not

hpet_assign_irq() sits not only in the boot path, but also in the

vector was already assigned prevents leaking previously assigned ones.
