I threw it at a random selection of configs and so far the only failures
I'm seeing are:

  lib/test_firmware.c:134:2: error: implicit declaration of function 'vfree' 
  lib/test_firmware.c:620:25: error: implicit declaration of function 'vzalloc' 
  lib/test_firmware.c:620:2: error: implicit declaration of function 'vzalloc' 
  security/integrity/digsig.c:146:2: error: implicit declaration of function 
'vfree' [-Werror=implicit-function-declaration]

Full results trickling in here, not all the failures there are caused by
this patch, ie. some configs are broken in mainline:
