about. It is tested with xm-test and by manually running the xm
commands. It also handles the return case (reported by Masaki Kanno)
that was missed in the originally patch.

call to determine the initial reservation separately from the amount of
memory to be freed up by ballooning -- when using QEMU, we lose 8 MiB to video
RAM, which must be accounted for when ballooning, but _not_ accounted for
within the domain's memory allocation.
Tidy this code up using the new architecture-specific interface arrangement.

Driver changes: Make backend drivers check it when entering Closed
state, only unregister devices when the "online" node is either "0" or
not present. The later maintains backward compatibility.
Tools changes: Update "online" node when creating and hot-unplugging
devices.
Background: When kexec'ing a new kernel, the old kernel's frontend
driver will shutdown, but the backend device should *NOT* disappear
due to that, so the new kernel instance can reconnect.

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.].

Apply the domain cpumask to each vcpu rather than mapping vcpus to
cpus in the list. This is more inline with the comments for the
cpus parameter and also allows the credit scheduler to balance
vcpus within the domain cpumask.

There are various reasons it should be daemonized, but the particular
problem we hit was that YaST called "xm create" and waited on output on
stdout/stderr; xm then spawned vncviewer (which never closed its
inherited stdout and stderr); xm then would exit, but YaST still had
open file descriptors, and therefore waited forever. It would be
possible to work around in YaST, but it seemed cleaner to daemonize
vncviewer.
