 CONFIG_RANDOM_GCM

Hi Sandy,

[auto build test ERROR on: char-misc/char-misc-testing]
[also build test ERROR on: v4.3 next-20151106]

url:    https://github.com/0day-ci/linux/commits/Sandy-Harris/A-couple-of-generated-files/20151107-223540
config: arm64-allyesconfig (attached as .config)
reproduce:
        wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        # save the attached .config to linux build tree
        make.cross ARCH=arm64 

Note: the linux-review/Sandy-Harris/A-couple-of-generated-files/20151107-223540 HEAD 4d000f20486e81f999bc1f5499f0cfb36b37db02 builds fine.
      It only hurts bisectibility.

All errors (new ones prefixed by >>):
