(trying this again, as first time, my message bounced)

I just saw this and have not followed the entire thread from the beginning, but if you are unsure if a given license text to something on the SPDX License List, I highly recommend using the SPDX License-diff browser extension / add-on (for Chrome or Firefox) - once you have that, you can simply highlight a text in your browser window and it will tell you if it matches or how far off it is if not.

If a license is NOT a match to anything on the SPDX License List, please submit it to the SPDX legal team here: https://tools.spdx.org/app/submit_new_license/ (and preferably then tag me in the Github issue, my Github ide is @jlovejoy ) Please make sure to include that it's in the LInux kernel and a link to where you found it. 

More about requesting a new license be added to the SPDX License List can be found here: https://github.com/spdx/license-list-XML/blob/master/DOCS/request-new-license.md

Thanks!

Several files are missing SPDX license identifiers.

Following files are given the following SPDX identifier based on the comments in the top of the file:

       include/asm/ibmebus.h:/* SPDX-License-Identifier: GPL-2.0 OR OpenIB BSD */

[...]

quoted

       platforms/pseries/ibmebus.c:// SPDX-License-Identifier: GPL-2.0 OR OpenIB BSD

"OpenIB BSD" is not a defined SPDX identifier. There is an SPDX
identifier "Linux-OpenIB"
https://spdx.org/licenses/Linux-OpenIB.html
but I believe that is not a match to what's in these files
(specifically, the wording of the disclaimer), rather I believe what
you want here is BSD-2-Clause, but you may want to check that.
