kobject: grab the kset reference in kobject_add, not kobject_init
kobject_init should not be grabing any references, but only initializing
the object. This patch fixes this, and makes the lock hold-time shorter
for when a kset is present in the kobject.
The current kernel tree has been audited to verify that this change
should be safe.

rpadlpar pci hotplug driver was doing some pretty bad stuff with the
sysfs files. This cleans up the logic to be sane and gets rid of the
gratuitous kset that is not needed for a simple directory like this.
Note, this patch is not even build tested, let alone run-time tested.
Someone with access to this hardware and can test would be greatly
appreciated.

There is no firmware "subsystem" it's just a directory in /sys that
other portions of the kernel want to hook into. So make it a kobject
not a kset to help alivate anyone who tries to do some odd kset-like
things with this.

Driver Core: kill subsys_attribute and default sysfs ops
Remove the no longer needed subsys_attributes, they are all converted to
the more sensical kobj_attributes.
There is no longer a magic fallback in sysfs attribute operations, all
kobjects which create simple attributes need explicitely a ktype
assigned, which tells the core what was intended here.

fix struct user_info export's sysfs interaction
Clean up the use of ksets and kobjects. Kobjects are instances of
objects (like struct user_info), ksets are collections of objects of a
similar type (like the uids directory containing the user_info directories).
So, use kobjects for the user_info directories, and a kset for the "uids"
directory.
On object cleanup, the final kobject_put() was missing.

Driver Core: add kobj_attribute handling
Add kobj_sysfs_ops to replace subsys_sysfs_ops. There is no
need for special kset operations, we want to be able to use
simple attribute operations at any kobject, not only ksets.
The whole concept of any default sysfs attribute operations
will go away with the upcoming removal of subsys_sysfs_ops.

Now ksets can be dynamically created on the fly, no static definitions
are required. Thanks to Miklos for hints on how to make this work
better for the callers.
And thanks to Kay for finding some stupid bugs in my original version
and pointing out that we need to handle the fact that kobject's can have
a kset as a parent and to handle that properly in kobject_add().
We don't need a "default" ktype for a kset. We should set this
explicitly every time for each kset. This change is needed so that we
can make ksets dynamic, and cleans up one of the odd, undocumented
assumption that the kset/kobject/ktype model has.
This patch is based on a lot of help from Kay Sievers.

It isn't that hard to add simple kset attributes, so don't go through
all the gyrations of creating your own object type and show and store
functions. Just use the functions that are already present. This makes
things much simpler.
Note, the version_str string violates the "one value per file" rule for
sysfs. I suggest changing this now (individual files per type supported
is one suggested way.)
