Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

net/sched/cls_api.c has overlapping changes to a call to
nlmsg_parse(), one (from 'net') added rtm_tca_policy instead of NULL
to the 5th argument, and another (from 'net-next') added cb->extack
instead of NULL to the 6th argument.

net/ipv4/ipmr_base.c is a case of a bug fix in 'net' being done to
code which moved (to mr_table_dump)) in 'net-next'. Thanks to David
Ahern for the heads up.

-Section 2 - Scope.
-
-    a. License grant.
-
-        1. Subject to the terms and conditions of this Public License, the
-           Licensor hereby grants You a worldwide, royalty-free,
-           non-sublicensable, non-exclusive, irrevocable license to
-           exercise the Licensed Rights in the Licensed Material to:
-
-            A. reproduce and Share the Licensed Material, in whole or in part; and
-
-            B. produce, reproduce, and Share Adapted Material.
-
-        2. Exceptions and Limitations. For the avoidance of doubt, where
-           Exceptions and Limitations apply to Your use, this Public
-           License does not apply, and You do not need to comply with its
-           terms and conditions.
-
-        3. Term. The term of this Public License is specified in Section 6(a).
-
-        4. Media and formats; technical modifications allowed. The Licensor
-           authorizes You to exercise the Licensed Rights in all media and
-           formats whether now known or hereafter created, and to make
-           technical modifications necessary to do so. The Licensor waives
-           and/or agrees not to assert any right or authority to forbid You
-           from making technical modifications necessary to exercise the
-           Licensed Rights, including technical modifications necessary to
-           circumvent Effective Technological Measures. For purposes of
-           this Public License, simply making modifications authorized by
-           this Section 2(a)(4) never produces Adapted Material.
-
-        5. Downstream recipients.
-
-            A. Offer from the Licensor - Licensed Material. Every recipient
-               of the Licensed Material automatically receives an offer
-               from the Licensor to exercise the Licensed Rights under the
-               terms and conditions of this Public License.
-
-            B. Additional offer from the Licensor - Adapted Material. Every
-               recipient of Adapted Material from You automatically
-               receives an offer from the Licensor to exercise the Licensed
-               Rights in the Adapted Material under the conditions of the
-               Adapter's License You apply.
-
-            C. No downstream restrictions. You may not offer or impose any
-               additional or different terms or conditions on, or apply any
-               Effective Technological Measures to, the Licensed Material
-               if doing so restricts exercise of the Licensed Rights by any
-               recipient of the Licensed Material.
-
-        6. No endorsement. Nothing in this Public License constitutes or
-           may be construed as permission to assert or imply that You are,
-           or that Your use of the Licensed Material is, connected with, or
-           sponsored, endorsed, or granted official status by, the Licensor
-           or others designated to receive attribution as provided in
-           Section 3(a)(1)(A)(i).
-
-    b. Other rights.
-
-        1. Moral rights, such as the right of integrity, are not licensed
-           under this Public License, nor are publicity, privacy, and/or
-           other similar personality rights; however, to the extent
-           possible, the Licensor waives and/or agrees not to assert any
-           such rights held by the Licensor to the limited extent necessary
-           to allow You to exercise the Licensed Rights, but not otherwise.
-
-        2. Patent and trademark rights are not licensed under this Public
-           License.
-
-        3. To the extent possible, the Licensor waives any right to collect
-           royalties from You for the exercise of the Licensed Rights,
-           whether directly or through a collecting society under any
-           voluntary or waivable statutory or compulsory licensing
-           scheme. In all other cases the Licensor expressly reserves any
-           right to collect such royalties.
-
-Section 3 - License Conditions.
-
-Your exercise of the Licensed Rights is expressly made subject to the
-following conditions.
-
-    a. Attribution.

-        1. If You Share the Licensed Material (including in modified form),
-           You must:

-            A. retain the following if it is supplied by the Licensor with
-               the Licensed Material:
-
-                i. identification of the creator(s) of the Licensed
-                   Material and any others designated to receive

-            C. indicate the Licensed Material is licensed under this Public
-            License, and include the text of, or the URI or hyperlink to,
-            this Public License.
-
-        2. You may satisfy the conditions in Section 3(a)(1) in any
-           reasonable manner based on the medium, means, and context in
-           which You Share the Licensed Material. For example, it may be
-           reasonable to satisfy the conditions by providing a URI or
-           hyperlink to a resource that includes the required information.
-
-        3. If requested by the Licensor, You must remove any of the
-           information required by Section 3(a)(1)(A) to the extent
-           reasonably practicable.  b. ShareAlike.In addition to the
-           conditions in Section 3(a), if You Share Adapted Material You
-           produce, the following conditions also apply.
-
-           1. The Adapter's License You apply must be a Creative Commons
-              license with the same License Elements, this version or
-              later, or a BY-SA Compatible License.
-
-           2. You must include the text of, or the URI or hyperlink to, the
-              Adapter's License You apply. You may satisfy this condition
-              in any reasonable manner based on the medium, means, and
-              context in which You Share Adapted Material.
-
-           3. You may not offer or impose any additional or different terms
-              or conditions on, or apply any Effective Technological
-              Measures to, Adapted Material that restrict exercise of the
-              rights granted under the Adapter's License You apply.
-
-Section 4 - Sui Generis Database Rights.
-
-Where the Licensed Rights include Sui Generis Database Rights that apply to
-Your use of the Licensed Material:
-
-    a. for the avoidance of doubt, Section 2(a)(1) grants You the right to
-       extract, reuse, reproduce, and Share all or a substantial portion of
-       the contents of the database;
-
-    b. if You include all or a substantial portion of the database contents
-       in a database in which You have Sui Generis Database Rights, then
-       the database in which You have Sui Generis Database Rights (but not
-       its individual contents) is Adapted Material, including for purposes
-       of Section 3(b); and
-
-    c. You must comply with the conditions in Section 3(a) if You Share all
-       or a substantial portion of the contents of the database.

-    replace Your obligations under this Public License where the Licensed
-    Rights include other Copyright and Similar Rights.
-
-Section 5 - Disclaimer of Warranties and Limitation of Liability.
-
-    a. Unless otherwise separately undertaken by the Licensor, to the
-       extent possible, the Licensor offers the Licensed Material as-is and
-       as-available, and makes no representations or warranties of any kind
-       concerning the Licensed Material, whether express, implied,
-       statutory, or other. This includes, without limitation, warranties
-       of title, merchantability, fitness for a particular purpose,
-       non-infringement, absence of latent or other defects, accuracy, or
-       the presence or absence of errors, whether or not known or
-       discoverable. Where disclaimers of warranties are not allowed in
-       full or in part, this disclaimer may not apply to You.
-
-    b. To the extent possible, in no event will the Licensor be liable to
-       You on any legal theory (including, without limitation, negligence)
-       or otherwise for any direct, special, indirect, incidental,
-       consequential, punitive, exemplary, or other losses, costs,
-       expenses, or damages arising out of this Public License or use of
-       the Licensed Material, even if the Licensor has been advised of the
-       possibility of such losses, costs, expenses, or damages. Where a
-       limitation of liability is not allowed in full or in part, this
-       limitation may not apply to You.
-
-    c. The disclaimer of warranties and limitation of liability provided
-       above shall be interpreted in a manner that, to the extent possible,
-       most closely approximates an absolute disclaimer and waiver of all
-       liability.
-
-Section 6 - Term and Termination.
-
-    a. This Public License applies for the term of the Copyright and
-       Similar Rights licensed here. However, if You fail to comply with
-       this Public License, then Your rights under this Public License
-       terminate automatically.
-
-    b. Where Your right to use the Licensed Material has terminated under
-       Section 6(a), it reinstates:
-
-        1. automatically as of the date the violation is cured, provided it
-           is cured within 30 days of Your discovery of the violation; or
-
-        2. upon express reinstatement by the Licensor.
-
-    c. For the avoidance of doubt, this Section 6(b) does not affect any
-       right the Licensor may have to seek remedies for Your violations of
-       this Public License.
-
-    d. For the avoidance of doubt, the Licensor may also offer the Licensed
-       Material under separate terms or conditions or stop distributing the
-       Licensed Material at any time; however, doing so will not terminate
-       this Public License.
-
-    e. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.
-
-Section 7 - Other Terms and Conditions.
-
-    a. The Licensor shall not be bound by any additional or different terms
-       or conditions communicated by You unless expressly agreed.

-       independent of the terms and conditions of this Public License.
-
-Section 8 - Interpretation.
-
-    a. For the avoidance of doubt, this Public License does not, and shall
-       not be interpreted to, reduce, limit, restrict, or impose conditions
-       on any use of the Licensed Material that could lawfully be made
-       without permission under this Public License.
-
-    b. To the extent possible, if any provision of this Public License is
-       deemed unenforceable, it shall be automatically reformed to the
-       minimum extent necessary to make it enforceable. If the provision
-       cannot be reformed, it shall be severed from this Public License
-       without affecting the enforceability of the remaining terms and
-       conditions.
-
-    c. No term or condition of this Public License will be waived and no
-       failure to comply consented to unless expressly agreed to by the
-       Licensor.
-
-    d. Nothing in this Public License constitutes or may be interpreted as
-       a limitation upon, or waiver of, any privileges and immunities that
-       apply to the Licensor or You, including from the legal processes of
-       any jurisdiction or authority.
