Make the vTPM hotplug script use the UUID of the vTPM instance for
associating it with its instance number rather than the name of the
domain.
Also change the cleanup in the xm test to use the atexit mechanism
rather than explicitly calling a function to clean up.

This patch implements DOMCTL_SENDTRIGGER_NMI hypercall for x86 hvm

'xm trigger [domain] nmi [vcpu]'.

When domains are destroyed/suspend-resume/migration using the Xen-API
things break due to the domid not having been reset. This patch fixes
this. This is the best place I found for fixing this problem. I could
not push this line into _stateSet() for the case of DOM_STATE_HALTED
and left a comment regarding this.

- Allow multiple ChineseWallTypes in a VM labels
- check for surfacing exceptions in the python code
- check for array sizes in the XML DOM in python
- properly display the labels when doing 'xm list --label' in xm's
non-Xen-API mode
- rely on the security checking hooks in xend to check access to the
block interface rather than doing this in xm.

This patch fixes the xc_map_grant_refs() function, which would fail
because, instead of passing the malloc()-ed ioctl argument pointer to
the ioctl, the address of this pointer was being passed instead.

Need to ensure all the code slice in the wakeup path still
existing. For this purpose, we have to use __devinit instead
of __init, since the former is null for CONFIG_HOTPLUG while
the latter always causes related code to be free-ed after
first boot.
Later when adding __init to some function, be sure to consider
wakeup case and cpu hotplug!

support is specific to PM, instead of for a run-time
single CPU hotplug which can be a separate task. See
embedded comment:
/*
* XXX: One important thing missed here is to migrate vcpus
* from dead cpu to other online ones and then put whole
* system into a stop state. It assures a safe environment
* for a cpu hotplug/remove at normal running state.
*
* However for xen PM case, at this point:
* -> All other domains should be notified with PM event,
* and then in following states:
* * Suspend state, or
* * Paused state, which is a force step to all
* domains if they do nothing to suspend
* -> All vcpus of dom0 (except vcpu0) have already beem
* hot removed
* with the net effect that all other cpus only have idle vcpu
* running. In this special case, we can avoid vcpu migration
* then and system can be considered in a stop state.
*
* So current cpu hotplug is a special version for PM specific
* usage, and need more effort later for full cpu hotplug.

Basic infrastructure for Xen S3 support with a common CPU
context save/restore logic for both 32bit and 64bit.
Wakeup code is split into two parts:
- the first locates after trampoline code, to share all the
tricks on the latter, like relocation base and identy mapping
- the 2nd part locates in xen code segment, to do the actual
CPU context restore

Once the presence of LPT1 is baked into a Windows guest, it gets upset
if it is subsequently removed. Hence we add the 'LTP1' device object
back into the ACPI DSDT, and remove IRQ 7 from the list of IRQs usable
by the PCI-ISA links.

This patch adds a couple of new commands for using the Xen-API
extensions for security policies. Older tools are converted to support
going through the Xen-API for their operations rather than doing the
operations directly in their own code.

drives to fix a hang during SLES 9 HVM guest installation.
Without this, the SLES 9 installer kernels (32 and 64 bit) were
getting inconsistent information from QEMU as to whether the
(emulated) IDE drives support write caching (which they do). So part
of the kernel thought write caching was enabled (and enabled the usage
of barrier writes) and part of it didn't, which triggered a bug in
which the same barrier write is submitted over and over again ...
Fixed by setting another bit in the WIN_IDENTIFY (IDE drive "identify"
command) response to indicate we really, truly support write caching.
