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 all of the staging ks7010 files 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.

Extra GPL text wording can be removed as it is no longer needed at all.

An issue is observed where mallocs are failing due to overcommit failure.
The failure happens when there is high ION page pool since ION page
pool is not considered reclaimable by the overcommit calculation code.
This change considers ion pool pages as indirectly reclaimable and thus
accounted as available memory in the overcommit calculation.

In ll_dir_ioctl(), the object lumv3 is firstly copied from the user space
using Its address, i.e., lumv1 = &lumv3. If the lmm_magic field of lumv3 is
LOV_USER_MAGIC_V3, lumv3 will be modified by the second copy from the user
space. The second copy is necessary, because the two versions (i.e.,
lov_user_md_v1 and lov_user_md_v3) have different data formats and lengths.
However, given that the user data resides in the user space, a malicious
user-space process can race to change the data between the two copies. By
doing so, the attacker can provide a data with an inconsistent version,
e.g., v1 version + v3 data. This can lead to logical errors in the
following execution in ll_dir_setstripe(), which performs different actions
according to the version specified by the field lmm_magic.

This patch rechecks the version field lmm_magic in the second copy.  If the
version is not as expected, i.e., LOV_USER_MAGIC_V3, an error code will be
returned: -EINVAL.
