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: i386-allyesconfig (attached as .config)
reproduce:
        # save the attached .config to linux build tree
        make ARCH=i386 

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 >>):

>> drivers/char/random.c:280:35: fatal error: generated/random_init.h: No such file or directory
   compilation terminated.
