[XEN][POWERPC] Allocate more memory than RMA for Dom0

The following patch will only effect Dom0 at the moment and allow it
to be created with memory larger than RMA.  It works by allocating
extents (AKA chunks) of memory of an order specified by the processor.
The extent size should be a value that is capabable of mapping a
"large page" so we use the 970s large page size.  These extents are
tracked by an extents list that simply tracks these page allocations
and what there mapping is.  Other sub-systems effected by this:
  - Dom0 OFD devtree /memory cleanup
  - log_large_page_sizes is now an array
  - Config for minumum Dom0 size

Caveats:
 - There is a hack around HTAB allocation because we currently
   allocate one at domain creation time, this will be correct by a
   patch to follow.
 - Dom0, or domains capable of mapping mfns byt have their extents be
   PFN=MFN

vif-route
script creates the following syslog error entry:
"/etc/xen/scripts/vif-route failed; error detected."

It appears that both of the problematic commands are actually
redundant
when destroying domains:
1. the interface is already gone (I assume because the domain frontend
is gone already)  --> ifdown does not do anything
2. the route is gone as well since the interface has disappeared -->
ip
route del does not do anything

Executing those redundant commands with "do_without_error" ensures
that
the script completes and cleans up iptables rules. The attached
RFC-patch only masks those commands when bringing down an interface,
so
that domain creation continues to fail in case of vif setup problems
(intended behavior).

Having the iptables cleanup called correctly by vif-route is important
to keep the iptables rule-set clean, otherwise antispoof rules
accumulate with every vif creation.

kfraser@localhost.localdomain [Fri, 25 Aug 2006 17:39:10 +0000 (18:39 +0100)]
Replace dom0_ops hypercall with three new hypercalls:
 1. platform_op -- used by dom0 kernel to perform actions on the
    hardware platform (e.g., MTRR access, microcode update, platform
    quirks, ...)
 2. domctl -- used by management tools to control a specified domain
 3. sysctl -- used by management tools for system-wide actions

Benefits include more sensible factoring of actions to
hypercalls. Also allows tool compatibility to be tracked separately
from the dom0 kernel. The assumption is that it will be easier to
replace libxenctrl, libxenguest and Xen as a matched set if the
dom0 kernel does not need to be replaced too (e.g., because that
would require vendor revalidation).

From here on we hope to maintain dom0 kernel compatibility. This
promise is not extended to tool compatibility beyond the existing
guarantee that compatibility will not be broken within a three-level
stable release [3.0.2, 3.0.3, etc.].
