| Message-ID | <s1NeG-gB-49@gated-at.bofh.it> |
Hi Linus,
please merge these kbuild changes for v4.8-rc1:
- GCC plugin support by Emese Revfy from grsecurity, with a fixup from
Kees Cook. The plugins are meant to be used for static analysis of the
kernel code. Two plugins are provided already.
- Reduction of the gcc commandline by Arnd Bergmann.
- IS_ENABLED / IS_REACHABLE macro enhancements by Masahiro Yamada
- bin2c fix by Michael Tautschnig
- setlocalversion fix by Wolfram Sang
Thanks,
Michal

Merged. However, there were two slightly different versions of this
commit in my tree:
> Kees Cook (2):

differing by $ARCH vs $SRCARCH. There were a few other changes in that
area too, so I'd really like you to verify the end result.
(I haven't pushed out yet, it's still doing the test builds, so if you
don't see it yet, wait a bit and the merge should be out soon. Unless
the test build shows problems, in which case it might be longer ;^)

But if you accidentally pushed the wrong version, sky is not going to fall. It's just that make ARCH=(i386|x86_64|um) will not do the compiler check, until a fix patch is merged. Michal

That's what I assumed, and that's the version I picked. There were
some other confusing changes in that area though, so I'd like the
involved people to give my resolution a second look, just to make sure
it's fine.

Awesome, yeah, it looks good and tests out correctly for me. Thanks! -Kees -- Kees Cook Chrome OS & Brillo Security
