Subject: linux-next: build failure after merge of the final tree

Hi all,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

powerpc64-linux-ld: drivers/built-in.o: In function `.gpiochip_is_requested':
(.text+0x4): sibling call optimization to `_savegpr0_29' does not allow automatic multiple TOCs; recompile with -mminimal-toc or -fno-optimize-sibling-calls, or make `_savegpr0_29' extern

I got more than 60000 of these messages before I killed the link. :-(  I
am not sure what has changed to do this, but it may have been masked for
the past few releases due to other linking problems.

I have left this broken for today.
