Extend 'xm dumppolicy' to support Xen-API
I am extending 'xm dumppolicy' to be used via the Xen-API. For this
there are two new functions in the ACM policy class:
- get the currently enforced policy including statistical data from
the hypervisor
- get the ACM 'ssidref' of a Domain. Since this may be a ACM-specific
variable or type (int) I put it into the ACM class.
I extended the Xen-API documentation with the two new functions.

[IA64] Kexec: Fix ia64_do_tlb_purge so that it works with XEN
Fix ia64_do_tlb_purge, its broken in too many ways
1. Call SET_PER_CPU_DATA before making any calls to GET_THIS_PADDR
to ensure that per-cpu data is set up correctly.
2. Use the per_cpu variable to derive CURRENT_STACK_OFFSET rather
than reading it from a kernel register. See 1) for explanation
of why.
3. In the VHPT pruning code, don't use r25 as ia64_jump_to_sal,
which branches to ia64_do_tlb_purge expects r25 to be preserved.
There seems no reason not to use r2 as per the other purges
done in ia64_do_tlb_purge. Furthermore use r16 and r18 instead
of r20 and r24 for consistency reasons.
4. Move __va_ul(vcpu_vhpt_maddr(v)) comment outside of

xend: Fix name uniqueness check (revert 15168:a717cb2fac90).
Changeset 15168:a717cb2fac90 altered check_name() in XendDomainInfo so
that it compares domain IDs instead of UUIDs. This breaks a number of
things
- You can no longer use 'xm new' to define a persistent config file for
a running guest. This breaks the key OS provisioning scenario where
you boot a kenrel+initrd for the installer, and at the same time
define a permanent config with pygrub.
- It lets you define multiple inactive guests with different UUIDs, but
the same name because all inactive guests have a domid of None. So
you can now end up with multiple guests with same name, which is
contrary to the goal implied by the patch which was name uniqueness.
It is unclear from the original commit logs just what scenario it was
trying to protect against, but the original checking of uniqueness
based on UUID was correct & is what was used in previous releases XenD.
