Make the syscon-reboot driver accept value and mask instead of
just value.
Prior to this patch, the property name for the value was 'mask'. If

We have now in place a mechanism for adding callbacks to a cache in
order to be able to implement object migration.
Add a function __move() that implements SMO by moving all objects in a
slab page using the isolate/migrate callback methods.

If many objects are allocated with the slab allocator and freed in an
arbitrary order then the slab caches can become internally fragmented.
Now that the slab allocator supports movable objects we can defragment
any cache that has this feature enabled.
Slab defragmentation may occur:
1.
We just implemented slab movable objects for the SLUB allocator. We
should test that code. In order to do so we need to be able to a number
of things
- Create a cache
- Allocate objects to the cache
- Free objects from within specific slabs of the cache
- Enable Slab Movable Objects for the
Create an ops field in /sys/slab/*/ops to contain all the callback
operations defined for a slab cache. This will be used to display
the additional callbacks that will be defined soon to enable movable
objects.
Display the existing ctor callback in the ops fields contents.

-F lists caches that support object migration.
-C lists caches that use a ctor.
Add command line options to show caches with a constructor and caches
with that are migratable (i.e. have isolate and migrate functions).
