tools: Always use sane upstream (`native') python paths
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.

vtd: fix multiple Dom0 S3 on hosts that support Queued Invalidation.
On such hosts we can't do multiple Dom0 S3 when VT-d is enabled.
The cause is: during the first S3 resume, init_vtd_hw() initializes
the invalidation function pointers to the register-based ones and later
enable_qinval() forgets to overwrite the flush function pointers to
queued-based ones, so actually Queued Invalidaton is enabled, but we
actually use the register-based invalidation function! Later during
the second Dom0 S3, in iommu_suspend() -> iommu_flush_all(), we try to
use the register-based invalidation functions to perform global flush
while Queued Invalidation is enabled, and this can cause a host reset
because VT-d spec says: when the queued invalidation is enabled,
software must submit invalidation commands only through the IQ (and
not through any invalidation command registers).
The attached patch fixes the buggy enable_qinval(). And in
iommu_resume(), we invoke iommu_flush_all() for safety.

cpuidle: suspend/resume scheduler tick timer during cpu idle state entry/exit
cpuidle can collaborate with scheduler to reduce unnecessary timer
interrupt. For example, credit scheduler accounting timer
doesn't need to be active at idle time, so it can be stopped at
cpuidle entry and resumed at cpuidle exit. This patch implements this
function by adding two ops in scheduler: tick_suspend/tick_resume, and
implement them for credit scheduler

x86: Core support for Intel MCA support
Those patches based on AMD and SUN's MCA related jobs.
We have latest rebase after SUN's latest improvements.
We will have late following patches for recovery actions. This is a
basic framework for Intel.
Some implementation notes:
1) When error happens, if the error is fatal (pcc = 1) or can't be
recovered (pcc = 0, yet no good recovery methods),
for avoiding losing logs in DOM0, we will reset machine
immediately. Most of MCA MSRs are sticky. After reboot,
MCA polling mechanism will send vIRQ to DOM0 for logging.
2) When MCE# happens, all CPUs enter MCA context. The first CPU who
read&clear the error MSR bank will be this
MCE# owner. Necessary locks/synchronization will help to judge the
owner and select most severe error.
3) For convenience, we will select the most offending CPU to do most
of processing&recovery job.
4) MCE# happens, we will do three jobs:
a. Send vIRQ to DOM0 for logging
b. Send vMCE# to Impacted Guest (Currently Only inject to impacted
DOM0)
c. Guest vMCE MSR virtualization
5) Some further improvement/adds for newer CPUs might be done later
a) Connection with recovery actions (cpu/memory online/offline)
b) More software-recovery identification in severity_scan
c) More refines and tests for HVM might be done when needed.
