Currently, the freezer treats all tasks as freezable, except for the kernel
threads that explicitly set the PF_NOFREEZE flag for themselves. This
approach is problematic, since it requires every kernel thread to either
set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't
care for the freezing of tasks at all.
It seems better to only require the kernel threads that want to or need to
be frozen to use some freezer-related code and to remove any
freezer-related code from the other (nonfreezable) kernel threads, which is
done in this patch.
The patch causes all kernel threads to be nonfreezable by default (ie. to
have PF_NOFREEZE set by default) and introduces the set_freezable()
function that should be called by the freezable kernel threads in order to
unset PF_NOFREEZE. It also makes all of the currently freezable kernel
threads call set_freezable(), so it shouldn't cause any (intentional)
change of behaviour to appear. Additionally, it updates documentation to
describe the freezing of tasks more accurately.

This patch adds support for DLPAR memory add to the eHEA driver. To detect
whether memory was added the driver uses its own memory mapping table and
checks for kernel addresses whether they're located in already known memory
sections. If not the function ehea_rereg_mrs() is triggered which performs
a rebuild of the mapping table and a re-registration of the global memory
region.

Since we have to be able to handle MD updates, having an in-tree
set of data structures representing the MD objects actually makes
things more painful.
The MD itself is easy to parse, and we can implement the existing
interfaces using direct parsing of the MD binary image.
The MD is now reference counted, so accesses have to now take the
form:
handle = mdesc_grab();
... operations on MD ...
mdesc_release(handle);
The only remaining issue are cases where code holds on to references
to MD property values. mdesc_get_property() returns a direct pointer
to the property value, most cases just pull in the information they
need and discard the pointer, but there are few that use the pointer
directly over a long lifetime. Those will be fixed up in a subsequent
changeset.
A preliminary handler for MD update events from domain services is
there, it is rudimentry but it works and handles all of the reference
counting. It does not check the generation number of the MDs,
and it does not generate a "add/delete" list for notification to
interesting parties about MD changes but that will be forthcoming.

For most pre-5705 devices, multiple link interrupts were being generated
for a single physical link change. The source of the interrupts was
determined to be unnecessary toggling of the MAC link polarity bit.
This patch changes the way the link polarity bit gets configured. Where
possible, code that dynamically configures the bit in response to link
changes has been replaced by code that configures the bit once during
initialization time and then leaves the bit alone.
For correctness, this patch also limits the use of the bit to those
devices where it is defined, namely devices before the 5705. This patch
also corrects the link polarity configurations for 5700 devices when
paired against a bcm5411 phy.

Gagan Arneja <gaagaan@gmail.com> pointed out that tg3_reset_task()
could potentially race with another thread calling tg3_full_lock()
such as the ethtool_set_xxx() functions. This may trigger the
BUG_ON() in tg3_irq_quiesce() or cause the irq_sync flag to be out-
of-sync.
I think the easiest way to fix this is to get the tp->lock first
before setting the irq_sync flag. This is safe to do because the
tp->lock is never grabbed by the irq handler. This change will
guarantee that the irq_sync flag updates will be serialized. We also
have to change one spot to call tg3_netif_start() (which clears the
irq_sync flag) before releasing the tp->lock.

All drivers need to unregister their devices in the module unload function.
While doing so they must hold the rtnl and atomically unregister the
rtnl_link ops as well. This makes the rtnl_link_unregister function that
takes the rtnl itself completely useless.
Provide default newlink/dellink functions, make __rtnl_link_unregister and
rtnl_link_unregister unregister all devices with matching rtnl_link_ops and
change the existing users to take advantage of that.
