Now that the SPDX tag is in all drivers/staging/vme/ files, that
identifies the license in a specific and legally-defined manner.  So the
extra GPL text wording can be removed as it is no longer needed at all.

This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text.  And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.

No copyright headers or other non-license-description text was removed.

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.

Fix up the remaining staging vme driver to have a proper SPDX
identifier, based on the license text in the file itself.  The SPDX
identifier is a legally binding shorthand, which can be used instead of
the full boiler plate text.

This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

*import* and sometimes *imp* (in genops.c), so to avoid confusion we just
named it imp everywhere.

The current error exit path in function cc_ivgen_init via label
'out' free's resources from the drvdata->ivgen_handle context.
However, drvdata->ivgen_handle has not been assigned to the
context ivgen_ctx at this point, so the resources are not freed.
Fix this by setting drvdata->ivgen_handle to ivgen_ctx as early
as possible so that the clean up error exit return path can free
the resources.

Instead of the cfs workitem library, use workqueues.

As lnet wants to provide a cpu mask of allowed cpus, it
needs to be a WQ_UNBOUND work queue so that tasks can
run on cpus other than where they were submitted.

This patch also exported apply_workqueue_attrs() which is
a documented part of the workqueue API, that isn't currently
exported.  lustre needs it to allow workqueue thread to be limited
to a subset of CPUs.

Several staging directories have TODO files that indicate a
subsystem will be removed in the future.

Using a status entry of "S:	Obsolete" helps indicate the
subsystem files should not be modified unnecessarily.

checkpatch also tests this setting and emits a warning that
the matching subsystem files should not be modified.

This might help avoid receiving patches that will be dropped.

LIBCFS_ALLOC

LIBCFS_APT_ALLOC() calls kvmalloc_node() with GFP_NOFS
which is not permitted.
Mostly, a kmalloc_node(GFP_NOFS) is appropriate, though occasionally
the allocation is large and GFP_KERNEL is acceptable, so
kvmalloc_node() can be used.

This patch introduces 4 alternatives to LIBCFS_CPT_ALLOC():
 kmalloc_cpt()
 kzalloc_cpt()
 kvmalloc_cpt()
 kvzalloc_cpt().

Each takes a size, gfp flags, and cpt number.

Almost every call to LIBCFS_CPT_ALLOC() passes lnet_cpt_table()
as the table.  This patch embeds that choice in the k*alloc_cpt()
macros, and opencode kzalloc_node(..., cfs_cpt_spread_node(..))
in the one case that lnet_cpt_table() isn't used.

When LIBCFS_CPT_ALLOC() is replaced, the matching LIBCFS_FREE()
is also replaced, with with kfree() or kvfree() as appropriate.

The size of the data structure is primarily controlled
