Hexagon: Add support for Qualcomm Hexagon architecture
v5 cover Hexagon: Add support for Qualcomm Hexagon architecture
Linus,
This is the fifth version of the patchset (with one tiny whitespace fix) to the Linux kernel to support the Qualcomm Hexagon architecture. I believe it has all the acks necessary and is ready for inclusion in your tree.
Please let me know if there's anything else you require of these patches.
Thanks,
Richard Kuo

Please let me know if there's anything else you require of these patches.
So there's something odd going on with the Sign-off's, which makes me unhappy. It also makes me wonder if the authorship is properly attributed.
Some of these things are signed off by Linas Vepstas. In fact, some of them are *only* signed off on by him, not by you. Which is definitely wrong. But it makes me wonder if the authorship is buggered up, and those patches maybe should have a "From: Linas Vepstas <[email protected]>" on them too.
Example of this: "[PATCH v5 12/36] Hexagon: Export ksyms defined in assembly files." (but 13/36, 31/36 and 36/36 were that way too).
Others are signed off by both Linas Vepstas and you, but in an odd order. Since you're sending them to me, I'd expect your sign-off to be last, but it isn't. So the sign-off sequence makes it look like they were sent by Linas, even though I got them from you.
So I'd like some clarification on this, and I do need *your* sign-off on them all since you're sending them to me.
You don't have to re-send, but you do have to explain whether perhaps Linas should be author (and why the odd order of sign-offs) and basically do a "yeah, I sign off on those patches" with a full listing of the patches in question so that I have it for the record.

OK, my mistake on these. Linas did author those patches, but clearly I'm in their path. So, I sign off on:
[PATCH v5 12/36] Hexagon: Export ksyms defined in assembly files. [PATCH v5 13/36] Hexagon: Support dynamic module loading. [PATCH v5 31/36] Hexagon: kgdb support files
[PATCH v5 36/36] Add extra arch overrides to asm-generic/checksum.h
Many other times, I was the author, and Linas also had contributions to the files as well, but again, if they're coming through me, my signed-off should be last. The From: is me because I imported all the files into git from what we were doing previously. The rest of the patches from now on should have proper authorship.
Thanks,
Richard Kuo
