Hello Linus,
This isn't a git pull request as I have no public repo available at the
moment, but the Hexagon port appears to be ready for inclusion in your
tree.
The patches have been available for some time on the mailing list and
been acked as well as have spent some time in linux-next. The latest
revision of the patch set is V5.
If you want, you can also pull the patch tarball from the Hexagon
kernel file area on codeaurora.org as mentioned in the cover email.
Thanks,
Richard Kuo

Subject: [PATCH v5 00/36] Hexagon: Add support for Qualcomm Hexagon architecture
This is the fifth version (and hopefully final prior to the merge window) of the
patchset to the Linux kernel to support the Qualcomm Hexagon architecture. It's
mostly just minor cleanups, largely in the debugging areas.
A brief summary of changes from the last patchset:
* die(): fixed spinlock issues and added misc debug code to match
other architectures
* fixed getregset/setregset ordering and struct size
* enable kgdb on kernel oops
* improved stack trace printing
* added user.h as part of headers install
* used correct IO access for timer regs
* removed IRQF_DISABLED from IPI handler
These patches are available on Code Aurora:
https://www.codeaurora.org/patches/quic/hlk/hexagon-linux-20111018.tar.gz
Thanks to everyone for their feedback!
