The patch which you mentioned fixes the second problem: now I can disable
CONFIG_RETPOLINE.
But, the first problem is still here: with defconfig and gcc v6.4.0, kernel
doesn't build, with this message:
~~~~
$ make
scripts/kconfig/conf --syncconfig Kconfig
You are building kernel with non-retpoline compiler.
Please update your compiler.
make: *** [arch/x86/Makefile:311: checkbin] Error 1
~~~~
I don't think that this is a proper behavior. I suggest to allow compilation
Best Regards,
Kirill
