Hi all,

After merging the kspp-gustavo tree, today's linux-next build (sparc64
defconfig) failed like this:

sparc64-linux-gcc: error: unrecognized command line option '-Wcast-function-type'; did you mean '-Wbad-function-cast'?

$ sparc64-linux-gcc --version
sparc64-linux-gcc (Custom f51944395b6aa154) 7.3.1 20180130

Caused by commit

  21078041965e ("Makefile: Enable -Wcast-function-type")

I have reverted that commit for today.

I am still reverting that commit ...

Gustavo, can you please switch this to using cc-option?

Yeah; I actually removed all the patches related to -Wcast-function-type
from my -next branch a few minutes ago:

https://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux.git/log/?h=for-next/kspp

I'm currently working on resolving all these conflicts in a separate branch
before merging them again in my -next tree.

Great; that sounds ideal. :) Thank you!

-Kees
