It hits an internal error, see:

Already being fixed, please take a look at the thread starting at
20161016002205.GA9686@vader; for your convenience I've put Nicholas Piggin's
initial work, my lousy but works-for-me fix for x86, Arnd Bergmann's for arm
at git@github.com:kilobyte/linux.git branch kbuild-exports.

raspberries, 0.4kg sugar; put into a big jar for 1 month.  Filter out and
throw away the fruits (can dump them into a cake, etc), let the drink age
at least 3-6 months.

Thanks.

So you have three patches on that branch, I cherry-picked the first
two and it is almost fixed except the __fentry__ thing which is still
missing a CRC, see below.

[ snip repeated failures of __fentry__ ]

Probably because of this:

#ifdef CC_USE_FENTRY
# define function_hook __fentry__
#else
# define function_hook mcount
#endif

[..]

Then you have this:

EXPORT_SYMBOL(function_hook)

which most likely exported the name "function_hook" and not
"__fentry__".

Does this patch fix things for you? If it does, I can make it more
generic (moving the MACRO_EXPORT_SYMBOL into the export.h header). And
submit that.

kbuild-exports+your patch makes all my warning go away and *yay* that kernel
even boots to console .. ( X mode broken but this seems to be a different issue )
